Measurement of insulation resistance on the power unit
In the course of the series testing, the power unit of the drive controller is tested
by applying 1.9 kV.
Should the measurement of insulation resistance be necessary in a system check,
then this can be carried out under the following conditions:
▪ an insulation test can be performed only for the power unit,
▪ to avoid impermissible high voltages, all connecting cables of the drive con-
troller must be disconnected prior to the test,
▪ a 500 V DC insulation tester is used.

Repairs
DANGER
Danger of injury through electric shock!
Non-observance of warnings may result in serious injury or damage.
 When the drive control is disconnected from the mains voltage, live device
parts and connections may not be touched immediately in case the condens-
ers are still live.
NOTICE
Risk of damage to the drive control!
If the information is not observed, the drive control could be damaged and
destroyed during subsequent start-up.
 Repairs to the drive control may only be performed by the manufacturer.
