Work on the electric parts of the machine may only be carried out by
skilled technicians.
The machine must not be opened until approx. 5 minutes after pulling
the plug from the socket to allow the integrated capacitors to dis-
charge.
Have maintenance carried out by trained personnel.
Possible errors:
As long as the green LED is lit, the circuit board is electrically charged
- even after you switch off the line voltage. The green LED goes out
when the condensers are discharged.
The diagnostic lamps built into the inverter, five red LEDs and a green
LED, help you troubleshoot any problems you may encounter.
However, this requires, that you open the inverter housing and apply
voltage. This must be carried out by a specialist or a properly
instructed employee.
