Installing and Connecting the Batteries
1.
Use the battery installation diagram that came with the UPS
batteries and cabinet as you follow the steps below.
2.
Place the external battery cabinet or rack as close as possible to the
FERRUPS UPS. If the batteries will be further from the unit than the
standard cables allow, contact your service representative or your
local distributor for assistance.
The external battery cabinet or rack should be well ventilated and
away from direct sunlight or other heat source. Ensure that the floor
is level and can support the weight of the batteries, the cabinet or
rack, and any other necessary equipment. Your Eaton sales
coordinator can tell you the size and weight of external batteries.
The temperature should be below 77
°
F (25
°
C) for the best battery
performance. Batteries will be less efficient at temperatures below
65
°
F (18
°
C). High temperatures will reduce battery life. Typically, at
about 95
°
F (35
°
C) battery life will be half of what it would be at a
normal temperature of 77
°
F (25
°
C). At about 113
°
F (45
°
C), battery
life will be one-fourth of normal.
The batteries should be as close as possible to the UPS to reduce
DC wiring costs and improve battery performance.
NOTE
If you are installing the batteries in a place where there may be seismic activity, you
should anchor the UPS and external battery cabinets to the floor. Anchoring kits are available
from Eaton.
3.
Wherever conductors may be exposed to physical damage, you
must protect the conductors in accordance with National Electrical
Code ANSI/NFPA 70-1993. This includes battery cables between
the UPS and the external battery cabinet and cables between
external battery cabinets (if you have more than one).
We suggest routing battery cables through flexible conduit. For
models with a removable DC plug at the UPS end of the cables, we
suggest routing the cables through the conduit to within about 12
I
(30.5 cm) of the UPS because the connector or plug does not
connect to flexible conduit. Install flexible conduit for battery cables
according to local or national code.
