CHAPTER 7 - Installation
7.1. Installing a Brand New G6-500NFC Module
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 G6-500NFC module
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 G6-500NFC 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 G6-500NFC. The pump or cabinet that the G6-500NFC 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 G6-500NFC.
b. The pump or cabinet must provide an Ethernet data connection. The requirements are:
i. Capable of at least 10Mbps (preferably 100Mbps).
ii. 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.
iii. Minimum cable standard should be Cat5e.
iv. 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.
5. Accessibility. The enclosure must be designed and mounted at a height so disabled persons are able to
operate the device. Height must be compliant with PCI 6.X standards.
6. Materials. The enclosure and all its components must be constructed of durable materials suitable for the
intended location.
7. Door cut-out. 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 G6-500NFC is rated for IPX6 on the customer facing side. The parts sitting inside the
pump/pedestal enclosure are designed to reduce the likelihood of water 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 G6-500NFC 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. Placement. The G6-500NFC must always be installed in an upright (vertical) position to a backward
maximum incline of 20 degrees.
G6-500NFC User Guide, DCV-00660 S2 R06
Page | 23
CHAPTER 8 - Tools Required to Mount the G6-500NFC
• 4 x M4 screws of the correct length to attach the OPT to your pump/cabinet.
Note: Screws are not provided with the product, for the two upper mounting locations, use 2 × M4 × 10 mm screws.
For the two lower mounting locations, use MS0162 – M4 × 12 mm screws, which are included in the A2-05 Fan Kit.

CHAPTER 15 - Tamper-Detection
The G6-500NFC is a secure device, and it contains various technologies that help it detect if someone tries to tamper
with it.
The terminal includes several tamper detection mechanisms such as temperature extremes, backup battery removal,
dis-assembly, and severe conditions, including mishandling or dropping the device may cause a tamper event.
If, on power-up or at any time when the G6-500NFC is powered, a tamper is detected, the G6-500NFC will
immediately lock out of “normal” operation and enter a “tampered” state. When this happens, the G6-500NFC 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 G6-500NFC will display this screen:
Tamper Detection
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 G6-500NFC to be returned to the factory for
service/ repair.

CHAPTER 16 - Basic Maintenance
16.1. Cleaning G6-500NFC (A2-05) Module
The G6-500NFC 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.
• Use an air duster (air can) with a max 2mm diameter straw to flush debris out of the ICC card slot. Insert in
the slot, some wiggling might be required to ensure it is fully inserted. Blow air into the ICC area to clear out
any dust or particulates.
• Then insert a Magnetic Head Cleaning Case into the ICC card slot 3-5 time. Repeat this on the MSR head.
Things to watch out for:
• Always clean off excess detergent.
• Do not use a high-pressure water stream to clean your G6-500NFC. Water pressure may damage the card
reader.
• Do not rub the display if it is dry – dust or dirt can scratch the anti-reflective coating.
• Do not use petroleum based solvent cleaners, they will damage the surface and shorten the life of your
product.
16.2. A2-05 Fan Kit Maintenance
The FlexPay 6 A2‑05 Fan Kit may only be maintained by authorized service personnel, as the fan is installed on the
rear of the G6-500NFC unit behind the dispenser door and is not accessible to normal users. Basic maintenance
checks include the following:
• Ensure the USB-C fan and its connector are free from visible damage.
• Check that the fan blades can rotate freely without obstruction.
• If the fan appears dirty but undamaged, clean it gently using a soft brush or an air duster (air can) with a max
2mm diameter straw to remove dust and debris. Avoid using liquids or solvents.
