Chapter 2. Safety & Compliance Information
STOP There are hazards and safety precautions associated with installing, inspecting, maintaining or
servicing this product.
Important: Before you start, READ! You need to understand the safety information in this manual.
Hazards and safety precautions for tasks are always listed.
Fire, explosion or electrical shock could occur and cause death or serious injury if these safe service
procedures are not followed.
2.1. Preliminary Precautions
Fuel stations can be a dangerous place to work - there are flammable fuels, vapours and high voltages.
You should only install, inspect, maintain or service this equipment when you are fully trained and
authorized to do so.
2.2. Safely Accessing a Fuel Pump
Evacuation and Barricading
If you need to access a pump/dispenser head, then you must:
• Evacuate all unauthorized persons and vehicles.
• Use safety tape or cones as a barricade to the affected unit(s).
Total Electrical Shut-Off
Before accessing the electrical components or the electronics of a pump/dispenser, you must carry out
a total electrical shut-off of that unit.
To shut off electricity find the switch or circuit breaker and turn it to the “off” position.
If you can’t turn off the power, STOP. Do not continue until the electricity has been safely turned off by
you or someone else.
Read the Manual
Read, understand and follow this manual and any other labels or related materials supplied with this
equipment. If you do not understand a procedure, call an Invenco-authorized service contractor.
Warning: For your own safety and that of others, you must understand the procedures before
beginning work.
DCV-00668 S2 R04 3
2.3. Follow the Regulations
Regulations exist to keep everyone safe.
You are expected to follow:
• OSH regulations.
• National regulations and codes.
• State regulations and codes.
• Local regulations and codes.
Note: If you do not install, inspect, maintain or service this equipment in accordance with these codes,
regulations and standards, it may affect the safe use and operation of the equipment, or lead to legal
citations with penalties.
2.4. Replacement Parts
Use only genuine Invenco supplied replacement parts on your installation.

violate local regulations.
2.5. Safety Symbols and Warning Words
Throughout this guide you will see warnings and notes in boxes like below. These are used to let you
know when you need to take extra caution in order to avoid hazards and/or potential injury to yourself
or another person.
Always follow these instructions!
Warning: This alerts you to a hazard or unsafe practice that could result in death or serious injury.
Note: This designates a hazard or unsafe practice which may result in minor injury or a legal issue.
2.6. Prevent Explosions and Fires
Fuels and their vapours will become explosive if ignited.
All fuels cause vapours when they are exposed to air and transferred between containers; spilled or
leaking fuels cause even more vapours.
When a customer’s tank is filled, vapours leak into the air around the tank and island, and these vapours
can potentially catch fire or explode if they are exposed to a spark or flame.
DCV-00668 S2 R04 4
This is why every single person on a fuel station forecourt must be aware of the danger of sparks and
open flames and take precautions to avoid explosions and fires.
No Open Flames
Open flames from matches, lighters, welding torches or other sources can ignite the fuel and vapours
present on forecourts.
There should never be an open flame on a fuel station forecourt for any reason.
No Sparks - No Smoking
Sparks can also start a fire or cause an explosion on a forecourt. Be safety conscious!
Do not:
1. Smoke.
2. Light a match.
3. Use a lighter.
4. Use a mobile phone outside of your car.
5. Start or use power tools.
6. Create a flame of any kind.
Also beware of:
1. Static electricity.
Always touch the metal of your vehicle after you get out of it to discharge any electrostatic charge before
you approach the dispenser island.
2.7. Working Alone
Best Practice
Always work with at least two people if possible; one to actively work and one as an assistant/backup.
Ideally if you are working around high voltages, the backup/assistant should be trained in providing
Cardiopulmonary Resuscitation (CPR).
Safety First!
Whether working alone or with someone else:
1. Advise station personnel where you will be working.
2. Warn station personnel not to turn the power back on while you are working on the equipment.
3. Use the OSH tag out and lock out procedures.
If you are not familiar with this requirement, refer to the information in the service manual and the
OSH documentation.

Chapter 7. Installation
7.1. Installing a Brand New OPT
In most cases a new installation must be done by the pump manufacturer, not a third party. Each pump
has safety certifications that can be invalidated if anyone other than the manufacturer modifies it.
Before a G6-400NFC (A2-09) can be installed, the pump enclosure must meet the following standards:
1. Fire.
The enclosure must be designed to meet the requirements of ISO/EN 60950-1 for fire
enclosures.
2. ATEX (Explosive Atmospheres).
The G6-400NFC (A2-09) has openings that prevent it being gas-tight. Because of this, it should
be installed away from all hazards. Refer to local laws and regulations for hazardous zones to
work out the best mounting place for the A2-09. The pump or cabinet that the A2-09 is mounted
in should also be designed to prevent a dangerous build-up of explosive gases.
3. Security.
The pump or cabinet should offer physical security to protect the public from the hazards within,
and to reduce the ability of anyone to tamper with the OPT.
4. Power & Data.
a. The pump or cabinet must provide mains power. The requirements are:
i. A permanently wired connection or a socket to plug it into.
ii. A protective earth connection.
iii. The outlet may be switched if it is a socket and must be switched if it is permanently wired.
iv. We recommend one Power Supply Unit (PSU) per G6-400NFC (A2-09) . The use of two
A2-09 on a single PSU may lead to erratic start up behaviour and is not recommended.
b. The pump or cabinet must provide an Ethernet data connection. The requirements are:
v. Capable of at least 10Mbps (preferably 100Mbps).
vi. The connection must be either a socket into which a standard Ethernet patch cable can
be connected, or a cable that is terminated in a standard RJ45 plug suitable for direct
connection into the OPT LAN socket.
vii. Minimum cable standard should be Cat5e.
c. The enclosure may provide an alternative data connection for terminals that have optional
communications modules installed. Please consult with Invenco for what options are available.
DCV-00668 S2 R04 16
5. Accessibility.
The enclosure must be designed and mounted so that disabled persons are able to operate the
OPT. Height must be compliant with PCI 6.X standards. The G6-400NFC (A2-09) has an
optional ADA kit that can be purchased and installed if required in order to meet this compliance.
6. Materials.
The enclosure and all its components must be constructed of durable materials suitable for the
intended location.
7. Door cut-out.
d. Use the wireframe in Chapter 22 Drawings at the end of this manual to determine the extra
space required for the front of the terminal (the terminal is larger than cut-out).
e. The edge of the cut-outs should be smooth and free of burrs, and the surface of the door around
the cut-out should be clean, and planar within ± 1mm.
8. Water Tightness.
The G6-400NFC (A2-09) is rated for IP66 for the front except the printer which is IP54.
The parts sitting inside the pump/pedestal enclosure are designed to reduce the likelihood of rain
splashes entering the electronics but the enclosure must provide protection from water.
The door should have a water seal against the enclosure, and there should be good drainage
and/or a system to reduce excessive condensation build-up and dripping.
9. Protection from Weather Extremes. | While the G6-400NFC (A2-09) is intended for use
outdoors, exposure to direct sunlight and/or heavy rain can affect customers’ experience using
the product. | The pump or enclosure should provide a canopy that prevents the OPT from being
exposed to direct sunlight and heavy rain. | If the OPT cannot be protected from direct sunlight, a
warning sign should be provided close to the OPT advising that the screen may become too hot
to touch.
10. In humid climates where the temperature regularly falls below 5°C it is probable that occasional
condensation will occur overnight inside the OPT cabinet, which can cause printer paper jams. In
this case, it is recommended, in the absence of any other heat source, that a thermostatic heater
is installed inside the cabinet, with attention to possible overheating.
11. Placement.
The G6-400NFC (A2-09) should be installed a maximum of 20° from vertical position, or in
accordance with instructions for an Invenco supplied Retrofit Kit.
12. Hinging.
Use the following diagrams as a guide when designing an enclosure and/or door to house the G6-
400NFC (A2-09). This will ensure there is a clearance between the A2-09 housing and the opening.
Note: Invenco Recommends Right-side hinging only. Hinging on the left side may cause cables
to be pulled out.
DCV-00668 S2 R04 17
Hinging Option 1 – Side Hinge (recommended)
For models without an internal printer, or for models with a printer where the paper has been mounted
with the spindle moving right to left through the paper roll (with the point to the center of the terminal):

Chapter 11. Power Supply Considerations
The G6-400NFC (A2-09) has been certified using a one-to-one ratio of A2-09 to power supply unit. All
other configurations are not certified.
There is one power supply certified for use worldwide the G6-400NFC (A2-09) .
• Meanwell HLG-185H-24
This power supply also requires a UL-listed Barrier Block with an approved Fire Enclosure, for
connecting its output to the EK0171 low-voltage DC cable. This power supply may also require a
Barrier Block or other UL-approved connector block for mains connection if its pre-installed wires
cannot be connected directly into the cabinet mains wiring.
Suitable barrier blocks are:
o TE Connectivity “Buchanan” 1546670-4
o Marathon “Kulka” 601 GP 04
DCV-00668 S2 R04 24
o
Chapter 12. G6-400NFC (A2-09) Wiring
Three connections need to be made to the G6-400NFC (A2-09):
1. Protective Earth.
2. Ethernet LAN.
3. DC Power supply.
The DC power supply cable also needs to be connected to the power supply.
12.1. Protective Earth
The G6-400NFC (A2-09) is provided with an Earth Tab and is recommended to be earthed.
The tab must be connected to the pump (or cabinet) frame to provide protection from both power faults
and static discharges. The earth wire thickness must be minimum 1.5mm
2
(or 16awg) and both it and
the earth stud must meet local regulations.
Fig. 12.1: Protective Earth
12.2. Ethernet LAN
The Ethernet cable is plugged into the correct connector on the rear of the G6-400NFC (A2-09) :
Fig. 12.2: Ethernet connection
DCV-00668 S2 R04 25
12.3. DC Power Supply
The low-voltage DC cables are plugged into the correct connectors on the rear of the G6-400NFC
(A2-09) :
Fig. 12.3: Low-voltage DC cables
The low-voltage DC cable carries the part number EK0171, and it can be obtained from Invenco
partner companies.
Chapter 13. Main Power Supply Wiring
The other end of the low-voltage DC Cables are connected into the AC-DC power supply:
Fig. 13:1 Power Supply Wiring
Warning: Once all the wiring to the power supply terminals has been completed, install the terminal
cover (TBC-07) to prevent accidental contact with the live mains connections
Installation within dispensers require specific, approved instructions for every variation of cabinet, and
is beyond the scope of this guide.
Please consult with Invenco for instructions and Retro-Fit Kits that are available for many dispenser
models.
Chapter 14. Wiring Completion
When all the cables have been installed, use cable ties to provide strain relief.
Ensure that all cables are tidy and cannot become snagged or pinched when the door of the cabinet is
opened and closed.
Warning: Local regulations may also require that the installation is electrically tested and certified
BEFORE switch-on, and periodically over the life of the unit
Chapter 15. First Power-Up
Once the installation is complete and the wiring is certified (if necessary), the main power can be
switched on.
15.1. Normal Start-Up
The G6-400NFC (A2-09) takes a couple of minutes to complete its start-up phase.
During this, several standard information screens will display.
There may be other screens as well, depending on customer configuration.
Start-up screen:
Fig. 15.1: G6-400NFC (A2-09) Start up screen.
Connecting to ethernet screen:
Fig. 15.2: Trying to establish ethernet connection.
DCV-00668 S2 R04 29
When the terminal has successfully connected to the Ethernet LAN it will display the following screen:
Fig. 15.3: Ethernet connection established.
After this the start-up will continue. The screens that are presented will vary depending on individual
customer configuration.
If a screen showing “One moment please…” is presented, it means that the G6-400NFC (A2-09)
requires its configuration to be set up. Please follow the directions in Invenco Document DCV-00260.
Fig. 15.4: Service App settings are available.
15.2. Edit Configuration
The G6-400 should have been configured during staging; however sometimes things change, and you
may need to modify various settings.
Please see Invenco document DCV-00260 for information on accessing and changing the G6-400NFC
(A2-09) configuration options; alternatively, your helpdesk will be able to assist you over the phone.
Chapter 16. Tamper-Detection
The G6-400NFC (A2-09) is a secure device, and it contains various technologies that help it detect if
someone tries to tamper with it.
Occasionally a G6-400NFC (A2-09) tamper-detection may be triggered after the device has been
staged and before installation, e.g. if the A2-09 was dropped onto a hard surface, that may trigger a
tamper-detection event.
If, on power-up or at any time when the G6-400NFC (A2-09) is powered, a tamper is detected, the A2-
09 will immediately lock out of “normal” operation and enter a “tampered” state. When this happens, the
A2-09 will not process any transactions and, depending on the nature of the tamper it may be almost
completely unresponsive.
If a tamper has been detected, after power-up the A2-09 will display a screen similar to this:
Fig. 16.1: Tamper has been detected.
The lights in the Card Reader slot will flash RED at about five times per second (i.e. rapid) if a
Destructive Tamper has been detected:
A Destructive Tamper cannot be restored on-site and requires the G6-400NFC (A2-09) to be returned
to an Invenco Service Centre for service/repair.
Chapter 17. Basic Maintenance
17.1. Cleaning
The G6-400NFC (A2-09) is designed to be low maintenance.
Daily cleaning:
Wipe with a soft damp cloth using only water.
If dirt or grime builds up:
• Use a diluted mild detergent and wipe with a soft cloth.
• Dry the screen using a lint-free or microfiber cloth.
Things to watch out for:
• Always clean off excess detergent.
• Do not use a high-pressure water stream to clean your G6-400NFC (A2-09) . Water pressure may
damage the card reader or printer chute.
• Do not rub the screen if it is dry - dust or dirt can scratch the anti-reflective coating on the screen
protector.
• Do not use petroleum based solvent cleaners, they will damage the surface and shorten the life
of your product.
• Over time the printer may build up dust and/or debris from the paper cutting function. Please do
not clean this yourself - refer cleaning to a qualified service agent.
