114201I – System Installation Manual
14
A qualified electrician familiar with battery systems and required precautions must
install and service the batteries. Any battery used with this unit shall comply with the
applicable requirements for batteries in the standard for emergency lighting and power
equipment, UL 924 (Canada’s National Building Code). Cabinets are design to be used
with, and batteries must be replaced with, manufacturer battery number BAT-CG12105
for some models and battery number BAT-CG12205 for other models or a
manufacturer approved equivalent (see the battery wiring diagram that came with the
battery cables). If you substitute batteries not supplied by manufacturer, the unit’s UL
(cUL) listing is void and the equipment may fail. Installation must conform to national
and local codes as well. Keep unauthorized personnel away from batteries.
The electrician must take these precautions:
Wear protective clothing and eyewear. For battery systems >48vdc, wear rubber
gloves and boots. Batteries contain corrosive acids or caustic alkalis and toxic
materials and can rupture or leak if mistreated. Remove rings and metal wristwatches
or other metal objects and jewelry. Don’t carry metal objects in your pockets where the
objects can fall onto the batteries or into the system or battery cabinet.
Tools must have insulated handles and must be insulated so that they do not short
battery terminals. Do not allow a tool to short a battery terminal to another battery
terminal or to the cabinet at any time. Do not lay tools or metal parts on top of the
batteries, and do not lay them where they could fall onto the batteries or into the
cabinet.
Install the batteries as shown on the battery-wiring diagram provided with the system.
When connecting cables, never allow a cable to short across a battery’s terminals, the
string of batteries, or to the cabinet.
Align the cables on the battery terminals so that the cable lug does not contact any part
of the cabinet even if the battery is moved. Keep the cable away from any sharp metal
edges.
CAUTION
Install the battery cables so the battery cabinet or the system doors cannot pinch them.
External battery cabinet chassis ground (or earth) must be connected to the system’s
chassis ground (or earth). The ground conductor must be insulated. If you use conduit,
this ground conductor must be routed in the same conduit as the battery conductors.
Where conductors may be exposed to physical damage, protect conductors in
accordance with the National Electrical Code (NEC) or [Canadian Electrical Code
(CEC)].
If you are replacing batteries or repairing battery connections, follow the procedure in
the system user’s Guide to shut down your system and remove both AC and DC input
power.
