3G-SC200 Data-Voice-Video Power Solutions Installation Guide

Warnings

This section contains important warnings. Read these warnings before installing or operating
a Powerware Data-Voice-Video Power Solutions DC power system.
Electrical Safety
•
The DC earth/ground link must be rated to carry the combined fault current of battery strings.
See details on page 20.
•
If the DC power system is to be installed in a location where the ambient temperature may rise
above 50ºC (122ºF), then V110 rated cable must be used for all connections.
•
The DC power system is not compatible with IT (Impedance Terra) AC power distribution
topologies. For advice refer to Worldwide Support on page 93.
•
A registered electrician (or suitably qualified person) must check the integrity of the installed
cabling, BEFORE the DC power system is powered up.
•
Commissioning must be performed in the sequence documented in this guide.
Location and Environment
•
For ease of access and to maintain optimum system cooling observe the clearances stated on
page 18.
•
Dust build-up within the DC power system may cause premature failure. In dusty environments
filter the ventilation air entering the equipment room. Ensure regular cleaning of the air filters.
•
Do not allow water or any foreign object to enter the DC power system. Do not place objects
containing liquid on top of or near the unit.
•
Flooded cell and VRLA lead acid batteries can emit explosive gases and must be installed with
adequate ventilation. Refer to the battery manufacturer or supplier for advice on minimum
ventilation levels.
Reverse Polarity
•
Always check that the battery cables have been terminated to the correct system polarity
BEFORE connecting the batteries or closing the battery disconnect device. Connecting batteries
to the DC power system with incorrect system polarity will damage the rectifiers and void all
warranty claims.
Hazardous Energy Levels
•
Rectifiers and batteries contain hazardous energy levels. Only personnel trained and
experienced in DC power systems are to service this equipment.
•
Always use insulated tools.
•
Do not short-circuit the live and common bus bars or cables.
