CAUTION
Risk of flashover!
High voltages will be present in the terminal compartment. High voltages can
cause flashover between conductors with different electric potential, and
between a conductor and earth.
Maintain the following minimum clearances:
-
-
- Connect the feeder cable conductors to busbars
• 1U1, 1V1, 1W1, 2U1, 2V1, 2W1 (12-pulse and 24-pulse drive, Fig. 7-9)
• 3U1, 3V1, 3W1, 4U1, 4V1, 4W1 (24-pulse drive, Fig. 7-9)
- Connect the motor cables to busbars U2, V2, W2 (Fig. 7-9).
- Connect the screens of all conductors and the shields of all cables to the PE ground busbar
(1 in Fig. 7-9).
- Connect the equipotential bonding conductor to the PE ground busbar.
- Tie the cables to the strain relief rails (2 in Fig. 7-9).
