Connecting the transfer switching equipment to the main circuit

WARNING

Hazardous voltage!

Ensure there is no live voltage before connecting the transfer switching equipment to the main circuit.

NOTICE

System damage if equipment is not installed properly

Connect the network with phase equality.

NOTE

Use of bridging bars and auxiliary conductor terminals

Mount the bridging bars and the auxiliary conductor terminals before connecting the transfer switching equipment to the main circuit. For information, see the sections titled Connecting the bridging bar on the load side and Connecting the auxiliary conductor terminal.
