3.3.6 Cabling Procedure Once the equipment has been finally positioned and secured, connect
the power cables as described in the following procedure.
Study the connection diagrams in figures 3-5.
1. Verify that the UPS equipment is totally isolated from its external
power source and all the UPS power switches are open.
Connect the AC input supply cables between the mains distribution
panel and the UPS rectifier input supply busbars and tighten the
connections to 5.4 Nm. If a separate- bypass supply is not provided
ensure the links are fitted between the rectifier input supply busbars
and the bypass input supply busbars (see figure 3-5).
ENSURE CORRECT PHASE ROTATION.
If a separate bypass supply is provided, connect the UPS bypass input
supply cables between the bypass distribution panel and the UPS
bypass input supply busbars and tighten the connections 5.4 Nm.
Ensure that any links fitted between rectifier input and bypass busbars
are removed (see figure 3-5).
ENSURE CORRECT PHASE ROTATION.
