Operating Guide
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
If done improperly, doing voltage withstand tests can damage the drive.
-
Megohmmeter testing is the only recommended test type for field installations.
Only a qualified field service engineer is allowed to perform this test.
Refer to the proper high potential/megohmmeter testing instructions in the service guide.
WARRANTY
If the power modules are opened, the warranty is not valid.
-
Do not open the power modules.
PERSONAL PROTECTIVE EQUIPMENT AND APPROVED TOOLS
When doing electrical work on the AC drive, always use personal protective equipment (PPE) and tools which are approved for
work with medium-voltage devices.
