The RT 10Kva requires very little maintenance. The batteries are valve-regulated, non-spillable,
flame retardant, lead acid and should be kept charged to obtain their design life.
The UPS continuously charges the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is essential to plug the UPS in for at least 24 hours
every four to six months to ensure full recharge of the batteries. Failure to recharge the batteries
periodically will permanently degrade battery capacity.
The RT 10Kva is designed to allow the user to safely replace the internal batteries. Read the safety
cautions before proceeding. Contact your local distributor or sales representative to
obtain the appropriate replacement battery kit part number and pricing.

Battery Replacement

CAUTION
!
A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed before replacing the batteries:
• Remove rings, watches and other metal objects.
• Use a Phillips (crosshead) screwdriver with insulated grips.
• Do not lay tools or other metal objects on top of the batteries.
• If the battery replacement kit is damaged in any way or shows signs of leakage, contact
your local distributor or sales representative immediately.
• Do not dispose of batteries in a fire. The batteries may explode.

12.1.1 Internal Battery Replacement Procedures

Both battery packs should be replaced at the same time.
1. Gently remove the front bezel by unscrewing
the side mounted screws.
2. Loosen the three screws on the front battery
cover grille. Lay the battery cover grille aside for
reassembly.
3. Remove the battery brackets at the bottom front
of the battery pack.
4. Grasp each battery pack assembly individually
and pull each out of the front of the UPS. Be
prepared to support the weight of the battery as
it is withdrawn.
5. Unpack the new battery assemblies taking care
not to destroy the packing. Compare new and
old battery assemblies to make sure they are the
same. If so, proceed with the next step. If they
are different, STOP and contact your local
distributor, sales representative or the Technical Support Group.
6. Line up and slide in the new replacement battery packs.
7. Reinstall the brackets on the front of the battery pack.
8. Reconnect the slotted battery cable connectors.
9. Reattach the front battery door, tightening the three screws.
10. Reattach the front metal bezel to the UPS.
NOTE
These are hot-swappable replacement batteries. However, caution should be exercised because
during this procedure the load is unprotected from disturbances and power outages.
