C.2
Checklist for electrical installation
Logbook
Use the checklist below to guide you through the electrical installation procedure for the drive.
Read the safety information at the start of these operating instructions before you start working
on the device.
Note
If the option in question is part of the delivery, check this accordingly in the right-hand column.
Check the boxes once you have finished the installation procedure to confirm that the activities
are complete.
Activity
If the drive is shipped in more than one transportation unit due to its
dimensions, you must also establish the electrical connections be‐
tween the cabinet units as well as the mechanical connections. In
addition to the power busbars, establish the electrical connection for
the signal and monitoring electronics.
Dimension and install the line and motor-side power cables in ac‐
cordance with the ambient and wiring conditions. Make sure that the
maximum cable lengths between the drive and motor are not excee‐
ded.
The motor ground must be routed back directly to the cabinet unit.
The cables must be properly connected with a torque of 50 Nm to the
drive terminals.
The cables for the motor and low-voltage switchgear must also be
connected with the required torques.
The medium-voltage switchgear is a central component of the drive
protection concept. For this reason, medium-voltage circuit-breaker
control must be integrated in the drive controller.
The medium-voltage circuit-breaker must be equipped with an un‐
dervoltage coil.
If the medium-voltage switchgear does not have an undervoltage coil
or a UPS-supported auxiliary-voltage supply, provide the following
alternative:
● Integrated circuit-breaker (option N13) on the secondary side of
● Capacitor-release units (option N20 or N21) for the circuit-
Set the overcurrent protection for the medium-voltage circuit-breaker
so that it protects the system.
To relieve strain on the cables, they must be clamped on the cable
propping bar (C-bar).
When EMC-shielded cables are used, screwed glands that connect
the shield to ground with the greatest possible surface area must be
provided on the motor terminal box.
