Battery Cabinets; External Battery Disconnect - Powerware 9315 Operation Manual

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. Most
UPS models can support up to four battery cabinets.

External Battery Disconnect

A breaker switch 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 1: There is no DC disconnect device within the UPS.
Note 2: The DC input to the UPS is protected by internal fuses F21 and F22.
Note 3: 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).
