Situation Check Items Solution
The Battery Low LED is
illuminated.
The UPS is on battery power
and the battery is almost
exhausted. The UPS will
shutdown shortly. When the
Utility power returns recharge
the battery.
The Fault LED is
illuminated.
Disconnect the connected
equipment. Turn the UPS off
and then back on again. If
the Fault LED is still on call for
Service. If the Fault LED is not
on, your equipment probably
has a short-circuit.
System fails to backup
when Utility fails.
The batteries may be bad or
weak. Charge the batteries
for 24-hours and then retest.
If the UPS works properly after
recharging, then the batteries
were weak. If the UPS does
not work properly, then the
batteries are bad and need to
be replaced.
The UPS is working
properly but the
connected equipment
does not turn on.
Check to see if all
the power cords
are properly
connected. Use a
voltmeter to check
the UPS’s output
receptacles for the
proper voltage.
If the power cords are properly
connected and the UPS has
the proper output voltage, then
your equipment has a
problem. If there is no output
voltage, then the UPS is being
controlled by the software,
disconnected the RS232 cable
from the UPS and restart the
UPS. If there is still no
output, call for Service.
Strange noise and
smell coming from the
UPS.
Immediately turn off the UPS.
Disconnect the input power
cord from the wall outlet and
call for Service.

5.4. Replacing the Batteries
(QUALIFIED SERVICE PERSONNEL ONLY)
The CPE On-Line Series UPS has an easy to replace batteries. Please read
all of the WARNINGS and CAUTIONS before attempting to service the
batteries.
• 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. The repairs and the Battery replacement must be performed by
QUALIFIED SERVICE PERSONNEL ONLY.
• CAUTION – Do not open or mutilate batteries. Released electrolyte is
harmful to the skin and eyes and may be toxic.
• 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 MINUTEMAN.
• CAUTION – Although battery system voltages are 36VDC, 72VDC and
96VDC 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 precautions 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).
4. Wear rubber gloves and boots.
5. Do not lay tools or other metal parts on top of batteries.
6. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
7. Determine if the battery is inadvertently grounded. If the battery 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.
