Guidelines for inspecting the insulation resistance (high-voltage test)
WARNING
An insulation resistance inspection under high-voltage conditions can damage the motor
insulation!
If insulation resistance inspections need to be carried out on a machine/plant with direct
If insulation resistance inspections need to be carried out on a machine/plant with direct
drives or directly on the motors (e.g. installation inspection, preventative maintenance,
troubleshooting), only inspection devices that comply with EN 61557-1, EN 61557-2, and
EN 61010-1 (or the relevant IEC standards) can be used.
The inspection may only be carried out with a maximum direct voltage of 1000 V for a
The inspection may only be carried out with a maximum direct voltage of 1000 V for a
maximum time of 60 s! The test voltage should be measured with respect to ground or the
motor enclosure. If a higher DC or AC voltage is necessary for the purposes of inspecting
the machine/system, you must arrange the inspection with your local Siemens office.
Please follow the operating instructions for the test device!

Inspections of the insulation resistance on individual motors must always be carried out as
follows:
1. Connect all winding and temperature sensor connectors with each other; inspection
1. Connect all winding and temperature sensor connectors with each other; inspection
voltage not to exceed 1000 VDC, 60 s against PE connection.
2. Connect all temperature sensor connectors to the PE connector and all winding
connectors with each other; the inspection voltage must not exceed 1000 VDC, 60 s,
winding against PE connector.
Each insulation resistance must be at least 10 MΩ, otherwise the motor insulation is
defective.
