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

6.7.2. Connecting the cables

CAUTION
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. 6-16)
– Motor cables to the busbars inside the COU (Fig. 6-18)
– Ground cable to the PE ground busbar
