Uninterruptible Power Supply
CAUTION!
The battery may present risk of electrical shock. Do not dispose of batteries in a fire as it may explode.
Follow all local ordinances regarding proper disposal of batteries.
CAUTION!
Do not open or mutilate the batteries. Released electrolyte is harmful to skin and eyes and may be toxic.
CAUTION!
The battery can present a high risk of short circuit current and electrical shock. The short circuit current
capability of the battery is sufficient to burn wire or tools very rapidly, producing molten metal. Observe these
precautions when replacing the battery:
1.
Remove all watches, rings or other metal objects.
2.
Only use tools with insulated handles.
3.
Do not lay tools or metal parts on top of battery or any terminals.
4. Wear protective eye wear (goggles), rubber gloves, and boots.
5.
Disconnect the charging source before connecting or disconnecting the battery terminals.
6. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source of the
ground. Contact with a grounded battery can result in electrical shock! The likelihood of such shock will
be reduced if such grounds are removed during installation and maintenance (applicable to a UPS and a
remote battery supply not having a grounded circuit).
Note:
DO NOT DISCONNECT the batteries while the UPS is in Battery Mode.
The EBPs can be replaced when the UPS is ON, but be aware that if the utility fails at that time, the load of the UPS
may NOT be protected.
Replacing Battery Trays in UPS and EBPs
If the batteries fail and need to be replaced following these steps.
1.
Remove the front cover of the UPS and/or EBPs.
2.
Remove the connection cables between the EBP and the UPS. Remove the screw on the baffle of the EBP
as shown in figures below, then remove the baffle from the left or right.
3.
Grasp the handle in front of the battery tray, pull the battery tray out of the UPS or EBP carefully.
4. Hold the middle of the new battery tray and insert it into the slot in the UPS or EBP. Once installed, make
sure it is completely inserted into the chassis.
