MAINS DISCONNECTION DEVICE
If the AC drive is used as a part of a machine, the machine manufacturer must supply a mains disconnection device (refer to EN
60204-1).
MALFUNCTION OF FAULT CURRENT PROTECTIVE SWITCHES
Because there are high capacitive currents in the AC drive, it is possible that the fault current protective switches do not
operate correctly.
VOLTAGE WITHSTAND TESTS
Doing voltage withstand tests can damage the drive.
Do not do voltage withstand tests on the AC drive. The manufacturer has already done the tests.
