4.2 HA32A UPS Cabinet
Before making any electrical connections, check that all ac input feeder circuit breakers
or fused switches that will interface with the UPS cabinet are in the off position. In
addition, make certain that the UPS cabinet ac input (MAINS1) circuit breaker Q1, the
bypass ac input (MAINS2) switch Q4S, the manual bypass switch Q3BP, and the UPS
cabinet output isolation switch Q5N are in the off position. Also, make sure that the
circuit breaker QF1 on the UPS Battery Cabinet is in the off position.
All field wiring connections for the UPS cabinet are made in the lower-right portion of
the UPS enclosure (Figure 4–1). To gain access to this area, the right front door of the
UPS cabinet must be unlocked and opened, and the inside cover panel removed. Cables
may enter either through the bottom of the UPS cabinet (Figure 2–2 or Figure 2–3), or
through the side of the UPS cabinet (Figure 2–1), whichever is the most convenient for
your installation.
A minimum 24-inch rear access area for the UPS cabinet is required once the UPS
cabinet and its auxiliary equipment have been installed. Local codes may require more
rear access area.
NOTE
The HA3000 series UPS may or may not be considered a separately derived
system and may be a part of a premise’s wiring under the National Electrical
Code. All input and output connections must be made in accordance with the
National Electrical Code (ANSI/NFPA 70) and with local codes as applicable.
