3.2 BATTERY
The UPS module shall use a valve regulated sealed lead acid heavy-duty industrial battery,
designed for auxiliary power service in a UPS application. The primary battery shall be furnished
with impact resistant plastic cases and housed in a matching cabinet(s) next to the UPS module.
A.
Protection Against Deep Discharge and Self-Discharge: The UPS shall be equipped with
a device designed to protect the battery against deep discharge, depending on discharge
conditions, with isolation of the battery by a circuit breaker. In particular, a monitoring device
shall adjust the battery shutdown voltage as a function of a discharge coefficient to avoid
excessive discharge at less than the rated output. A second device shall avoid self-discharge
of the battery into the UPS control circuits during an extended shutdown of the UPS (over two
hours).
B. Battery Self-Tests: The battery monitoring system shall be able to perform the following
automatic functions:
Battery circuit checks every twelve hours
Open-circuit battery test once a month
Partial discharge test every three months
This self-test system shall signal faults via LEDs on the front panel or a message to remote
supervision systems.
4.0 OPTIONAL
ACCESSORIES
A. Extended Battery Cabinet: Matching battery cabinets shall be furnished in both adjacent or
stand alone versions. The cabinet shall match the height and depth of the UPS module and
shall have a width of 26”, 36, 48” per battery cabinet. All power wiring and control cables shall
be included for adjacent models (remote cabinet cables provided by customer)
B. External Control and Communications Devices
Up to three of the following control and communications devices may be installed in the UPS
module:
1. RS232/U-Talk or Dry Contacts Card (66060): The U-Talk protocol shall be used with
Solution-Pac 2 for remote monitoring or graceful shutdown for most popular file servers.
The dry contacts will close on predefined conditions to monitor UPS operations.
Requires one communication slot and optional cables. The dry contacts will close on the
conditions listed below, but shall be user programmable to close on preset thresholds of
other user UPS parameters:
UPS on Line
Load on Bypass
UPS on Battery
Low Battery Warning
Battery Fault
General Alarm
Two (2) dry contact inputs shall also be provided to turn the UPS inverter on and off
remotely upon closure of the contacts. This feature may also be disabled if required.
