72 Installation checklist
Make sure that ...
The drive module is fastened properly to the enclosure.
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.
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 (un-
painted) 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.
Appropriate DC fuses are installed, if necessary.
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.
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. The conductor is connected to the correct terminal, and the terminal is tightened to the
correct torque.
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 connec-
ted 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 cable 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.
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.
