CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM/PDU/DISTRIBUTION

CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM

a. Normal Operation

b. Battery Operation

c. Bypass Operation

d. Common Fault

e. Low Battery

f. UPS Off

H. Communication Interface Board: A communication interface board shall provide the

following communication ports which can be used simultaneously:

1. RS232 Serial Port #1

2. RJ-45 Interface port for a Remote Display

2.8 BATTERY

A. The UPS battery shall be of modular construction made up of user replaceable, hot

swappable, fused, battery modules. Each battery module shall be monitored for voltage

and temperature for use by the UPS battery diagnostic, and temperature compensated

charger circuitry.

B. The battery jars housed within each removable battery module shall be of the Valve

Regulated Lead Acid (VRLA) type.

C. The UPS shall incorporate a battery management system to continuously monitor the

health of each removable battery module. This system shall notify the user in the event

that a failed or weak battery module is found.

PART 3 – ACCESSORIES

3.1 BATTERY DISCONNECT BREAKER

A. Each UPS system shall have a 250 VDC rated, thermal magnetic trip molded case

circuit breaker. Each circuit breaker shall be equipped shunt trip mechanisms and

1A/1B auxiliary contacts. The circuit breakers are to be located within the UPS

enclosure or as part of a line-up-and-match type battery cabinet.

3.2 MAINTENANCE BYPASS PANEL

A. The UPS cabinet shall include an integrated three-switch maintenance bypass panel

(MBP). The MBP shall provide power to the critical load from the bypass source,

during times where maintenance or service of the UPS is required. The PDU/System

bypass shall provide a mechanical means of complete isolation of the UPS from the

critical output distribution.
