Danger
Danger of electrical shock!
The compact inverters may be opened only by HEIDENHAIN service
engineers.
Do not engage or disengage any terminals while they are under power.
Danger
IEC 61800-5-1 requires a non-detachable connection to the line power
supply.
Note
If the power supply is other than 400 V, an autotransformer is required. It
must comply at least with the connection specifications of the subsequent
compact inverter.
With a power supply of 400 V, the inverter voltage U
