Safety instructions when working with battery
EXTERNAL BATTERY MUST BE INSTALLED AND CONNECTED TO THE
UPS BY QUALIFIED SERVICE PERSONNEL.
INSTALLATION PERSONNEL MUST READ THIS ENTIRE SECTION AND
REFER TO THE BATTERY MANUFACTURERS INSTALLATION MANUAL
BEFORE HANDLING THE UPS AND BATTERY.
UPS INTENDED TO BE USED WITH A REMOTE BATTERY SUPPLY – ALL MODELS:
“PLEASE REFER TO THE BATTERY MANUFACTURER’S INSTALLATION MANUAL FOR
BATTERY INSTALLATION AND MAINTENANCE INSTRUCTIONS”.
DANGER!
Full voltage and current are always present at the Battery Terminals.
The Battery used in this system can provide 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.
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 un-insulated Battery Terminals.
A qualified service person that is familiar with Battery systems and required precautions must install and
service the Battery.
The installation must conform to national and local codes.
Keep unauthorized personnel away from Battery.
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 Battery, and do not lay them where they could fall onto
the Battery or into the cabinet.
3 Install the Battery as shown on the drawing provided with the Battery.
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 the UPS or Battery Cabinet Doors cannot pinch them.
6 Do not connect the Battery Terminal to Ground.
If any Battery Terminal is inadvertently grounded, remove the source of the ground.
Contacting any part of a grounded Battery can cause a risk of electric shock.
7 To reduce the risk of fire or electric shock, install the Battery in a temperature and humidity
controlled indoor area, free of contaminants.
8 Battery System Chassis Ground (earth) must be connected to the UPS chassis ground (earth).
If you use conduit, this ground conductor must be routed in the same conduit as the Battery
Conductors.
9 Where conductors may be exposed to physical damage, protect the conductors in accordance with
all applicable codes.
10 If you are replacing Battery or repairing Battery Connections, shut OFF the UPS and remove the
Battery Fuses or open the Battery System disconnect.
