4. Electrical connection
To guarantee the electrical interference protection of the module, the
housing must be connected to GND (e.g. to the ground of the vehicle).
To protect the whole system (dialogue module and wiring ) the individual
electric circuits must be protected.
The supply cables, interfaces and inputs/outputs (CR1056) are connected via M12
connectors on the back of the unit.
Connector 1 (male):
supply, CAN interface
Connector 2 (female):
RS232 interface, CAN interface
Connector 3 (female):
inputs / outputs
Connector 4 (female):
Ethernet
For the pin connection of the connectors see the "technical data", CR1055 (page
29) and CR1056 (page 31).
Screen signal cables in EMC-critical applications.
To prevent corrosion between the connectors and the diecast zinc housing
of the unit, do not use any sockets with stainless steel fitting.
Do not connect or disconnect the serial interface while live.
Connecting or disconnecting the serial interface while live can lead to un-
defined states, causing damage to the RS-232 driver module.
