6.4 Battery Cabinets
You can enhance the protection time provided by your UPS by adding one or more battery
cabinets. The battery cabinets provided by the UPS manufacturer are equipped with sealed
lead-acid, maintenance-free batteries in a cabinet that matches the UPS. Each battery
cabinet contains a battery circuit breaker. Several battery capacities are available.
The UPS battery cabinets can be paralleled. With this capability, you can increase your
battery backup time by adding battery cabinets to your UPS system. The Powerware 9315
can support up to four battery cabinets.
6.5 External Battery Disconnect
A breaker is located inside each battery cabinet supplied by the UPS manufacturer.
However, due to space limitations, your battery cabinets may not be located in the same
area as your UPS. An optional external DC circuit breaker provides a manual means of
disconnecting a battery that is located remotely from the UPS. The circuit breaker is
enclosed in a wall-mounted box. You can install it anywhere between the remote DC
supply and the UPS, according to national and local codes.
The breaker switch should be set to ON for normal UPS operation when DC power is
available at the UPS. When service personnel are performing maintenance on the UPS or
battery cabinet, the switch should be set to OFF.
NOTE
There is no DC disconnect device within the UPS.
NOTE
The DC input to the UPS is protected by internal fuses F21 and F22.
NOTE
The UPS DC disconnect trip signal from TB4, points 1 and 2 (shunt trip) or TB4,
points 1 and 3 (UV trip) must be connected to the DC source disconnect device(s).
