Please observe the following guidelines for set-up:
• Power supply lines should only be laid as pairs, as close together as possible.
• Sensitive signal lines should be shielded to achieve highest possible damping,
and under this shielding they should be still be laid out twisted.
• Metal plug connections should be used for shielded lines.
• Cable bundles should be distributed in accordance with their purpose (e.g.
HF, LG, and power supply); the groups thus formed should not be routed
parallel to the extent possible, and they should be routed with clearance.
The OPUS A3 relies on a connection to an ECU that controls the functions and
features of the target vehicle/machine.

Please keep all the connectors separated. All connection should be done on the
shortest distance to the unit.
4.3.1 Unused plugs
ACHTUN
4.3.2 Power Supply
The unit may be used with the 12 V and for 24 Volt battery systems, operating
voltage range of 8-36 VDC. The overvoltage resistance is about 48V for 2 minutes.
Inverse-polarity protection is up to -48 V DC.
Car ground (pin no. 4 on main connector) has to be connected to the chassis by a
conductor as short as possible. Even if there is no conductive chassis available (eg.
in E-vehicles) the pin has to be connected to the negative pole of the battery.
Otherwise there will be no protection against over voltage, shot cut or ESD.
4.4 First steps
Plug the main connector into the OPUS A3. Then connect the pins 15 and 30 for the
plus voltage, as well as pins for GND and CarGND for the ground. Switch on the
Power supply.
On start the boot-logo image will be displayed on the screen. This may be
exchanged with the customer specific image (please refer to C/C++ Developer
Guide for more information).
The boot up takes about 3 minutes and will call the application according to the start
scripts on the unit (start scripts for Projektor Tool and CODESYS© application
already installed by delivery).
Penetrating humidity by unused and unprotected plugs may
cause damage of the unit. Please protect unused plugs with the
special blind inserts that have been supplied with the units.
Th Wrong connection may cause damage of the unit.
The ECU must be the component in charge of all safety related
functions.

The application displays the information to the version of the application software
required. CODESYS© application also contains a simple function test. Each new
downloaded application will replace the old one automatically.
4.5 Cleaning/ service / maintenance
Cleaning agents which have an abrasive or dissolving effect on the coated glass
pane, the foil of the touch screen or the plastic of the encoder or the housing should
not be used to clean OPUS A3 operator panels. Only use soft clothes with a little
soap and water or mild dish washing liquid.
The OPUS A3 does not have any parts that require service by the user.
Repairs can only be performed by Topcon Electronics GmbH & Co KG.
4.6 Disposal
Dispose of the device in accordance with the national environmental regulations
