Make sure that …
The insulation resistance of the input power cable, motor cable and motor is measured
according to local regulations and the manuals of the drive.
The drive is attached securely on an even, vertical and non-flammable wall.
The cooling air flows freely in and out of the drive.
If the drive is connected to a network other than a symmetrically grounded TN-S system:
You have done all the required modifications (for example, you may need to disconnect
the EMC filter or ground-to-phase varistor). See the electrical installation instructions.
Appropriate AC fuses and main disconnecting device are installed.
There is an adequately sized protective earth (ground) conductor(s) between the drive
and the switchboard, the conductor is connected to correct terminal, and the terminal is
tightened to the correct torque.
Proper grounding has also been measured according to the regulations.
The input power cable is connected to the correct terminals, the phase order is correct,
and the terminals are tightened to the correct torque.
There is an adequately sized protective earth (ground) conductor between the motor and
the drive, and the conductor is connected to the correct terminal, and the terminal is
tightened to the correct torque.
Proper grounding has also been measured according to the regulations.
The motor cable is connected to the correct terminals, the phase order is correct, and the
terminals are tightened to the correct torque.
The motor cable is routed away from other cables.
No power factor compensation capacitors are connected to the motor cable.
The control cables are connected to the correct terminals, and the terminals are tightened
to the correct torque.
If a drive bypass connection will be used: The direct-on-line contactor of the motor and
the drive output contactor are either mechanically and/or electrically interlocked, that is,
they cannot be closed at the same time. A thermal overload device must be used for
protection when bypassing the drive. Refer to local codes and regulations.
There are no tools, foreign objects or dust from drilling inside the drive.
The area in front of the drive is clean: the drive cooling fan cannot draw any dust or dirt
inside.
Drive covers and cover of the motor connection box are in place.
The motor and the driven equipment are ready for power-up.
