4.2 Checklist for electrical installation

4.2 Checklist for electrical installation
Use the following checklist to guide you through the electrical installation procedure for the
cabinet unit. Read the safety information at the start of this operating manual before you start
working on the device.
Note
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
Power connections
1 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 / Connection cross-sections and cable lengths").
The motor ground must be fed back directly to the cabinet unit.
The cables must be properly connected with a torque of 50 Nm to the cabinet unit
terminals. The cables for the motor and low-voltage switchgear must also be connected
with the required torques.
2 The cables between the low-voltage switchgear and the cabinet unit must be protected
with line fuses to provide adequate conductor protection (VDE 636, Part 10). See
"Technical specifications" for the appropriate fuses.
3 For strain relief, the cables must be clamped on the cable propping bar (C-type
mounting bar).
4 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. On
the cabinet, the cables must be grounded with the clips supplied with the EMC shield
bus with the greatest possible surface area (shield bus supplied with option L00 or can
be ordered separately with option M70 – see "Electrical installation / EMC-compliant
installation").
5 The cable shields must be properly applied and the cabinet properly grounded at the
appropriate points (see "Electrical installation / EMC-compliant installation").
6 The voltage for the fan transformer in the Active Line Module (-G1-T10) and Motor
Module (-U1-T10) as well as the internal power supply (-A1-T10) must be set (see
"Electrical installation / Adjusting the fan voltage (-G1-T10, -U1-T10)" and "Electrical
installation / Adjusting the internal power supply (-A1-T10)").
7 Before the cabinet is operated from an ungrounded supply/IT system, the connection
bracket for the interference-suppression capacitor on the Active Interface Module (-A2)
must be removed (see "Electrical installation / Removing the connection bracket for the
interference-suppression capacitor with operation from an ungrounded supply").
8 The type plate can be used to ascertain the date of manufacture. If the period from the
date of manufacture to initial commissioning or the cabinet unit downtime is less than
two years, the DC link capacitors do not have to be reformed. If the downtime period is
longer than two years, they must be reformed in accordance with the description in the
"Maintenance and servicing" section.
