Installing the External Batteries and DC Disconnect (DCD)
External batteries must be installed and connected to the UPS by a qualified service person who
is familiar with UPS battery installations and applicable building and electrical codes. The
qualified service person should read this entire section before the UPS and batteries arrive.
DANGER!
Full voltage and current are always present at the battery terminals. The batteries used in this
system can produce dangerous voltages, extremely high currents, and a risk of electric shock.
They may cause severe injury if the terminals are shorted together or to ground (earth). You
must be extremely careful to avoid electric shock and burns caused by contacting battery
terminals or shorting terminals during battery installation. Do not touch uninsulated battery
terminals.
A qualified service person who is familiar with battery systems and required precautions
must install and service the batteries. The installation must conform to national and local
codes. Keep unauthorized personnel away from batteries.
The qualified service person must take these precautions:
1.
Wear protective clothing, such as rubber gloves and boots and protective eye wear.
Batteries contain caustic acids and toxic materials and can rupture or leak if mistreated.
Remove rings and metal wristwatches or other metal objects and jewelry. Do not carry
metal objects in your pockets where the objects can fall into the battery cabinet.
2.
Tools must have insulated handles and must be insulated so that they will not short
battery terminals. Do not allow a tool to short between individual or separate battery
terminals or to the cabinet or rack. 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.
3.
Install the batteries as shown on the drawing provided with the batteries. When
connecting cables, never allow a cable to short across a battery’s terminals, the string of
batteries, or to the cabinet or rack.
4.
Align the cables on the battery terminals so that the cable lug will not contact any part of
the cabinet or rack, even if the battery is moved. Keep the cable away from any sharp
metal edges.
5.
Install the battery cables so they cannot be pinched by the UPS or battery cabinet doors.
