below to Daisy Chain the Battery Packs.
1. Be sure to read the installation placement procedure, all of the cautions and
the safety precautions before Daisy Chaining the Battery Pack(s).
2. Make sure that the DC circuit breakers on the rear panel of the Battery
Packs are in the Off position. CAUTION: If the Battery Pack's DC circuit
breaker is in the On position, the battery voltage will be present at the open
end of the Battery Pack's external battery cable and external battery con-
nector.
3. Press the Off button on the front panel of the UPS.
4. Turn off the input circuit breaker on the rear panel of the UPS.
5. Turn off the Utility input circuit breaker at the service panel.
6. Remove the External Battery Connector cover from the UPS's rear panel and
the additional Battery Packs.
7. Verify, before plugging the external battery cable into the UPS's external
battery connector or the Battery Pack's external connector that they mate
red to red and black to black.
8. Connect the external battery cable from the first Battery Pack to the exter-
nal battery connector on the UPS.
9. Connect the external battery cable from the second Battery Pack to the ex-
ternal battery connector on the first Battery Pack.
10. Turn ALL of the DC circuit breakers on the rear panel of the Battery Packs
to the On position.

Replace the batteries with the same number and type as origi-
nally installed in the Battery Pack. These batteries have pres-
sure operated vents. These Battery Packs contain sealed non-
spillable maintenance free lead acid batteries.
CAUTION:
WARNING!
This Battery Pack contains potentially hazardous voltages. Do
not attempt to disassemble the Battery Pack beyond the battery
replacement procedure. These Battery Packs contain no user
serviceable parts. Repairs and Battery replacement must be per-
formed by QUALIFIED SERVICE PERSONNEL ONLY.
Do not open or mutilate batteries. Released electrolyte is harmful
to the skin and eyes and may be toxic.
CAUTION:
(QUALIFIED SERVICE PERSONNEL ONLY)
CAUTION:
Do not dispose of batteries in a fire. The batteries may explode.
The batteries in this Battery Pack are recyclable. Dispose of the
batteries properly. The batteries contain lead and pose a hazard
to the environment and human health if not disposed of properly.
Refer to local codes for proper disposal requirements or return
the battery to the supplier.
The battery system voltages are 240VDC. The battery system
can still present a risk of electrical shock. These batteries pro-
duce sufficient current to burn wire or tools very rapidly, producing
molten metal. Observe these precautions when replacing the bat-
teries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or discon-
necting the battery terminals.
6. Determine if the battery is inadvertently grounded. If the batt-
ery is, remove the source of the grounding. Contact with any
part of a grounded battery can result in an electrical shock.
The likelihood of such shock will be reduced, if such grounds
are removed during installation and maintenance.
CAUTION:
Please read all of the WARNINGS and CAUTIONS before attempting to service
the batteries.
