6. UPS Maintenance
Servicing should be performed by qualified service personnel knowledgeable of batteries and
l
required precautions. Keep unauthorized personnel away from batteries.
Batteries can present a risk of electrical shock or burn from high short circuit current. Observe
l
the following precautions: 1) Remove watches, rings, or other metal objects; 2) Use tools with
insulated handles; 3) Do not lay tools or metal parts on top of batteries, 4) Wear rubber gloves
and boots.
When replacing batteries, replace with the same type and number of batteries or battery packs.
l
Contact your service representative to order new batteries.
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
l
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
l
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and
l
eyes and may be extremely toxic.
Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source
l
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 (applicable to equipment and remote battery supplies not having a grounded
supply circuit).
ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors.
l
Attempting to alter wiring can cause injury.
Disconnect charging source prior to connecting or disconnecting battery terminals.

To remove the cover:
Remove the 2 fixing screws on the bottom of the cover.
Push upon the bottom of the cover and pull the cover toward you to unclip it from the cabinet.
A ribbon cable connects the LCD control panel to the UPS. Do not pull on the cable or disconnect
