4.2 Checklist for electrical installation
The following checklist guides you through the electrical installation procedure for the cabinet
unit. Read the "Safety Instructions" section at the start of these Operating Instructions before
you start working on the device.
Note
Checking the checklist
Check the boxes accordingly in the right-hand column if the activity applies to the cabinet
unit in your scope of supply. In the same way, check the boxes once you have finished the
installation procedure to confirm that the activities are complete.
Item Activity Yes Completed
Power connections
1 The electrical connections of the transport units must be established (see "Electrical
installation / Power connections / Electrical connection of separately shipped
transport units").
2 The line-side and motor-side power cables must be dimensioned and routed in
accordance with the ambient and routing conditions. The maximum permissible
cable lengths between the converter and motor must be observed depending on the
type of cable used (see "Electrical installation / Power connections / Connection
cross-sections and cable lengths").
The converter outputs connected in parallel must be connected to the motor with the
same phases.
The minimum cable lengths must be observed between the converter cabinet and a
motor with only one winding system brought out (see Section "Power connections,"
Subsection "Minimum cable lengths for motor connection to a motor with single
winding system").
It must be ensured that the cables between the individual converters and a motor
with only one winding system brought out are identical in length.
The PE ground at the motor must be fed back directly to the cabinet unit.
The cables must be properly connected to the cabinet unit terminals and tightened
with a torque of 50 Nm. The cables for the motor and low-voltage switchgear must
also be connected and tightened with the required torques.
3 The DC link of the transport units must be connected (see "Electrical installation /
Power connections / Connection of DC link connectors").
4 The cables between the low-voltage switchgear and the cabinet unit must be pro-
tected with line fuses to provide adequate conductor protection (DIN VDE 100,
Part 430 and/or IEC 60364-4-43) See "Technical data" for the appropriate fuses.
5 For strain relief, the cables must be clamped on the cable propping bar (C-type
mounting bar).
6 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 ter-
minal box. On the cabinet, the cables must be grounded over the greatest possible
surface area using the clips supplied with the EMC shield bus (Shielding bus sup-
plied with option L00 or can be ordered separately with option M70) (See chapter
"Electrical installation/EMC-compliant installation").
