Connecting The Cables; Checking The Cable Insulation - ABB ACS5000 User Manual

6.7.2. Connecting the cables

CAUTION
Risk of flashover! High voltages in the terminal unit can cause flashover between the
electric potential of different conductors and the electric potential of a conductor and
earth. When you route and connect the cables, maintain the following
minimum clearances:
→ 70 mm between cable lugs of conductors with a different potential
→ 70 mm between the cable lug of a conductor and the parts with earth potential
→ 30 mm between cables with a different potential

6.7.2.1. Checking the cable insulation

– Measure the insulation of each cable before connection and verify that the results are within
the specification of the cable manufacturer.
– Leave the conductors unconnected at both ends until the commissioning personnel has
given permission to connect them.
6.7.2.2. Connecting the cables
Connect the cables to their corresponding busbars:
– Transformer cables to the busbars inside the primary PCU (Fig. 67)
– Motor cables to the busbars inside the COU (Fig. 69)
– Ground cable to the PE ground busbar
