Make sure that …
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 disconnector have been installed.
There is an adequately sized protective earth (ground) conductor between the drive and the switchboard,
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.
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 regu-
lations.
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.
The energy storage has been equipped with fuses for protecting energy storage cable in a cable short-
circuit situation.
The energy storage has been equipped with a disconnecting device.
The input power cable has been connected to the appropriate terminals, the phase order is right, and
the terminals have been tightened to the proper torque.
There is an adequately sized protective earth (ground) conductor between the motor and the drive,
and the conductor has been connected to appropriate terminal, and the terminal has been tightened
to the proper torque. (Pull on the conductors to check.). Proper grounding has also been measured
according to the regulations.
The motor cable has been connected to the appropriate terminals, the phase order is right, and the
terminals have been tightened to the proper torque.
The motor cable has been routed away from other cables.
No power factor compensation capacitors have been connected to the motor cable.
The control cables have been connected to the appropriate terminals, and the terminals have been
tightened to the proper 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, ie, cannot be closed simultaneously.
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.
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 start.
The coolant connections between cubicles (if any) and to the cooling circuit are tight.
If the drive is equipped with a cooling unit: Refer to the cooling unit documentation for specific tasks.
