preliminary startup has been performed by authorized service personnel.
The preliminary startup verifies all electrical interconnections to ensure the
installation was successful and the UPS operates properly.
2. The following procedures are applicable for systems with the optional
internally installed rectifier input breaker CB1 and inverter output breaker
CB3.
3. For operation of the System Bypass Module (SBM) in a Multi-module
system, refer to the applicable SBM Installation and Operation manual
referenced in the "Introduction" of this manual.

Ensure the UPS circuit breakers are set as follows:
UPS Input Breaker (CB1)
UPS Battery Breaker or
Battery Disconnect (CB2)
UPS Output Breaker (CB3)
UPS Bypass Breaker (CB4)
Backfeed Protection Breaker (FBP) OPEN
NOTE: When feeder power is applied in steps 3 and 5, UPS circuit breakers CB1,
CB2, CB3, CB4 and FBP will charge, if not already charged.
