Safety instructions when working with Battery
Danger!
External Battery must be installed and connected to the UPS by Qualified Service Personnel.
Installation Personnel must read this entire section before handling the UPS and Battery.
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.
If the terminals are shorted together or to ground they may cause severe injury.
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 Battery.
The installation must conform to national and local codes.
Keep unauthorized personnel away from the Battery.
The qualified service person must take these precautions:
1
Wear protective clothing, such as rubber gloves and boots and protective eye wear.
Battery contain caustic acids and toxic materials and can rupture or leak if mistreated.
Remove rings and metal wristwatches or other metal objects and jewellery.
Do not carry metal objects in your pockets where the objects can fall into the Battery cabinet. High energy
through conductive materials could cause severe burns.
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
Disconnect charging source prior to connecting or disconnecting Battery terminals.
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 Battery, 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 in such a way that 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
Determine if Battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded Battery can result in electrical shock.
The likelihood of such shock can be reduced if such grounds are removed during installation and
maintenance.
8
To reduce the risk of fire or electric shock, install the Battery in a temperature and humidity controlled
indoor area, free of contaminants.
9
Battery system chassis ground (earth) must be connected to the UPS chassis ground (earth).
If you use conduits, this ground conductor must be routed in the same conduit as the Battery conductors.
10
Where conductors may be exposed to physical damage, protect the conductors in accordance with all
applicable codes.
11
If you are replacing the Battery or repairing Battery connections, shut OFF the UPS and remove the Battery
fuses.
