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:
1Wear 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.
2Tools 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.
3Install 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.
4Align 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.
5Install the Battery Cables so the UPS or Battery Cabinet Doors cannot pinch them.
6Do 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.
7To reduce the risk of fire or electric shock, install the Battery in a temperature and humidity controlled indoor area, free of contaminants.
8Battery 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.
9Where conductors may be exposed to physical damage, protect the conductors in accordance with all applicable codes.
10If you are replacing Battery or repairing Battery Connections, shut OFF the UPS and remove the Battery Fuses or open the Battery System disconnect.
