105 Storing the UPS and Batteries
You can store the
UNITY
/I UPS between -4
o
and 104
o
F (-20
o
and 40
o
C). However, BEST
recommends that the unit and batteries be stored between 59
o
and 77
o
F (15
o
and 25
o
C). This
temperature range or cooler allows batteries to have a longer shelf life. Recharge stored batteries
every 90 to 120 days.
106 Finding a Location for the UPS
Keep these guidelines in mind when you choose the location for the UPS system and the
batteries.
Place the UPS in a clean, dust-free environment, free of contaminants. The air must be free
to circulate around the UPS cabinet and any battery cabinets or racks.
Avoid placing the unit in direct sunlight or near other heat sources.
Make sure that the ambient temperature is 32
o
to 104
o
F (0
o
to 40
o
C).
Ideal temperature is 77
o
F (25
o
C).
NOTE: At 95
o
F (35
o
C), battery life will be about one-half of what it would be at a normal
temperature of 77
o
F (25
o
C). At 113
o
F (45
o
C), battery life will be about one-
fourth of normal.
Make sure that the floor can support the weight of the UPS, external batteries, and any other
necessary equipment. See
in Section 103 for weights and
floor loading specifications.
The unit can be placed close to walls as long as there is enough clearance for the front doors
to open. Required service clearance is 3 feet (914 mm) at the front and 3 feet (914 mm) at
the top of the unit. If possible, allow a minimum of 3 feet (914 mm) of clearance around the
entire unit for easier servicing.
All service access is from the front and top of the unit. Cable entry is from the bottom of the
unit.
Do not operate the UPS or batteries in a sealed room or container.
