Exposed live parts
Danger to life caused by electric shock!
►
Disconnect the appliance from the power supply.
►
Do not touch housing, frame or components.
►
Use residual-current-operated circuit-breaker if tests
have to be conducted while the appliance is live.
►
Ensure that the resistance of the protective conductor
does not exceed the standardised values.
Communication between the electronically components is via
a D-bus2.
The D-bus2 consists of a 3-pole line system. The 3 lines are
connected as follows:
• 13,5 V d.c. via GND
• GND (possibly power potential)
• Data line
The software can be manually imported (flashed). A connection with
the D-bus2 is established via the UDA.
