• Prior to connecting or disconnecting terminal, disconnect the charging
source.
• Determine if the battery is inadvertently grounded. If it is, remove the source
of the ground. Contact with any part of a grounded battery can result in an
electrical shock. The likelihood of such a shock is reduced if such grounds
are removed during installation and maintenance.
• When replacing batteries, use the same number of the same type of
batteries.
• Dispose of batteries according to your local codes for disposal requirements.
• Do not dispose of batteries in a fire. Batteries may explode when exposed to
flame.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin
and eyes. It may be toxic.
8.2 Performing preventive maintenance
The battery cabinets require very little preventive maintenance. However,
inspect the system when the UPS is serviced or at least once a year to verify
that the units are operating normally and that the batteries are in good condition.
8.2.1
Daily maintenance
Perform the following steps every day:
1.
Check the area surrounding the UPS system. Make sure that the area is
not cluttered, allowing free access to the unit.
2.
Check that the air intakes (vents on the front doors) and exhaust opening
(the back of the UPS cabinet sections) are not blocked.
3.
Make sure that the operating environment is within the parameters
and Chapter
.
4.
Check that the UPS is in the double conversion (normal) or HE-mode
(green normal status indicator is illuminated). If the red alarm status
indicator is illuminated, or the green status indicator for normal operation is
not illuminated, contact your service representative.
8.2.2
Monthly maintenance
Perform the following steps once a month:
1.
Check the system parameters on the control panel (see Section
).
2.
Check the UPS air filters (located behind the front door) and wash or
replace as necessary. See Figure
for filter location. Contact an Eaton
service representative for replacement filters. To remove the filters:
a.
Open the UPS front door by lifting the latch from the bottom and
turning to the right (counterclockwise) and swing the door open.
