ABB
18 (of 62) 3BHS135824 ZAB E01Rev. D ACS 6000 Commissioning Manual
Follow the checklist of the commissioning report regarding the motor
installation.
3.5 Power Cables
Three-phase cables with individually shielded conductors are the
preferred cable type for the ACS 6000. Single-phase cables can be
used if the cable length is less than 100 m. These cables must be
configured as shown in Figure 3-2.
Figure 3-2 Configuration of single-phase Cables
An additional grounding cable along the power cables prevents screen
overloading because of potential differences in the plant. This is
needed, if the cross section of the cable screens is less than 50% of
the cross section of one phase conductor.
Refer to the ACS 6000 User’s Manual, Chapter 9 – Electrical
Installation, section Busbars and Grounding and the Power Cable
Specification (document number: 3BHS125090).
Follow the checklist of the commissioning report regarding the power
cabling.
3.6 Protection Against Injuries
All earthing inspections described in the previous chapters must be
carried out carefully, to avoid any dangerous potential rise in any parts
that are subject to touching. Protections are checked as follows:
1 Protection covers inside converter cabinets must refitted if they
had been taken off.
If covers have to be removed for measuring purposes for instance,
warning signs and temporary covers must be used.
2 Cabinet door locks must be checked.
The door keys should be given exclusively to persons taking part in
the commissioning. The doors should be kept closed whenever
possible. This also helps to keep the cabinets clean.
