Electrical connections
Contact with the printed conductors on the control unit must be
avoided (electrostatic discharge).
Before using the heater for the first time fit the control unit cover to
prevent the illegal escape of hot air (heater overheating).
The cable passage can be placed at either the left or right side.
To ensure that the cable passage in the control unit cover seals perfectly,
the cable grommet is to be adjusted appropriately on the wiring harness.
12.3. Supply voltage connection
Ideally from the vehicle's central electrical system.
An additional blade terminal fuse holder is to be fitted to protect
the heater (supplied with the heater). The fuse holder may only be
installed in the interior of the vehicle.
