Make sure that …
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 in the supply unit manual.
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.
If the drive is equipped with a DC/DC converter unit: There is an adequately sized protective earth
(ground) conductor between the energy storage and the DC/DC converter, the conductor has been
connected to appropriate terminal, and the terminal has been tightened to the proper torque. Proper
grounding has also been measured according to the regulations.
If the drive is equipped with a DC/DC converter unit: The energy storage cable has been connected to
the correct terminals of the DC/DC converter and energy storage, and the terminals have been tightened
to the proper torque.
If the drive is equipped with a DC/DC converter unit: The energy storage has been equipped with fuses
for protecting energy storage cable in a cable short-circuit situation.
If the drive is equipped with a DC/DC converter unit: The energy storage has been equipped with a
disconnecting device.
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.
If an external brake resistor is connected to the drive: There is an adequately sized protective earth
(ground) conductor between the brake resistor and the drive, and the conductor is connected to the
correct terminal, and the terminals are tightened to the correct torque. Proper grounding has also been
measured according to the regulations.
If an external brake resistor is connected to the drive: The brake resistor is connected to the correct
terminals, and the terminals are tightened to the correct torque.
If an external brake resistor is connected to the drive: The brake resistor cable is routed away from
other cables.
The control cables are connected to the correct terminals, and the terminals are tightened to the correct
torque.
The voltage setting of the auxiliary voltage transformers (if any) is correct. See the electrical installation
instructions.
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.
