2.1 Types of System Control Cabinets
1. SCCT is a stand-alone cabinet containing system control logic for up to six UPS modules, static
bypass switch, manually operated disconnects for the static bypass switch, and two motor-
operated system breakers. The SCCT is painted the same color as the Liebert UPS, but does not
match the sheet metal style of the UPS.
2. SCCI has the system control logic, circuit breakers and static bypass switch integrated into a
switchboard cabinet manufactured by others.
3. SCCC is an integrated configuration like the SCCI with the static bypass switch rated for
continuous duty.
