Make sure that …
The cooling air flows freely in and out of the drive. Air recirculation inside the cabinet is not possible
(air baffle plates are on place, or there is another air guiding solution).
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.
The enclosures of the equipment in the cabinet have proper galvanic connection to the cabinet protective
earth (ground) busbar; The connection surfaces at the fastening points are bare (unpainted) and the
connections are tight, or separate grounding conductors have been installed.
The main circuit connections inside the drive cabinet correspond to the circuit diagrams.
The control unit has been connected. See the circuit diagrams.
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.
Cover(s) of the motor connection box are in place. Cabinet shrouds are in place and doors are closed.
The motor and the driven equipment are ready for power-up.
