Danger!
!
,
Switch off power supply.
,
Dangerous voltage: The power terminals may carry dangerous voltages for some time even if the
power supply is switched off. Wait for some minutes before starting to work at the frequency inverter.
GB
,
Make sure that the frequency inverter is de-energized.
,
Ground the motor-side grounding terminal.
,
Connect the motor.
,
Cables must be as short as possible.
,
Comply with the data of the motor type plate for star or delta connection.
,
Connect the conductor shielding of the motor cable to ground potential by means of the shielding
clamp.
,
Connect the conductor shielding to ground potential on both sides (near to the frequency inverter
and near to the motor).

Wiring of control cables
,
Use shielded control cables.
,
Connect the conductor shielding of the control cables to ground potential by means of the shielding
clamp.
,
Connect the conductor shielding to ground potential on both sides of the cable. Analog cables must
be grounded only on the inverter side.
,
The control cables must be separated from the motor cable and mains cable (not in the same cable
duct).
