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.
Item Activity
1 If the drive is shipped in more than one transportation unit due to its dimensions, you must
also establish the electrical connections between the cabinet units as well as the mechan‐
ical connections. In addition to the power busbars, establish the electrical connection for
the signal and monitoring electronics.
2 Dimension and install the line and motor-side power cables in accordance with the ambient
and wiring conditions. Make sure that the maximum cable lengths between the drive and
motor are not exceeded.
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.
3 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 undervoltage coil.
4 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 the transformer
● Capacitor-release units (option N20 or N21) for the circuit-breaker.
5 Set the overcurrent protection for the medium-voltage circuit-breaker so that it protects
the system.
6 To relieve strain on the cables, they must be clamped on the cable propping bar (C-bar).
7 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.
8 Apply the cable shields properly.
The cabinet must be properly grounded at the points provided.
9 An auxiliary supply (3-phase 380 VAC) must be provided for the auxiliary equipment (e.g.
cabinet fan / DC-link precharging). Refer to the "Technical specifications" for the drives
for details of current consumption. Protect the low-voltage feeder appropriately at the plant.
With respect to the phase sequence, make sure that fans rotate in the right direction.
