REPLACING THE BATTERY

WARNING!

This Uninterruptible Power Supply contains potentially hazardous
voltages.  Do not attempt to disassemble the UPS beyond the
battery replacement procedure.  This UPS contains no
user serviceable parts.  Repairs and Battery replacement must
be performed 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 UPS 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.

Although battery system voltages are only 24VDC, 48VDC and
72VDC the battery system can still present a risk of electrical
shock.  These batteries produce sufficient current to burn wire or
tools very rapidly, producing molten metal.  Observe these pre-
cautions when replacing the batteries:
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 disco-
     nnecting the battery terminals.
6.  Determine if the battery is inadvertently grounded.  If the batte-
     ry is, remove the source of the grounding.  Contact with any p-
     art 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:

The UPS has an easy to replace hot-swappable batteries.  Please read all of
the WARNINGS and CAUTIONS before attempting to service the batteries.
NOTE:  If there is a power interruption while replacing the hot-swappable

batteries, with the UPS on, the load will not be backed up.
