General: These instructions detail the proper procedure for
installing C&D Technologies' Powercom Division (C&D) NEBS
compliant battery racks. The following describes how to
locate, assemble, and load open-frame racks for C&D
battery mounting applications. Proper attention to these
instructions will help ensure safe, trouble-free performance.
Rack Location: Locate racks in a clean, cool, dry place so
the batteries are not affected by sources of radiant heat,
such as sunlight, heating units, radiators, steam pipes, etc.
Variations of more than 5F (3C) between cells may
cause the battery to float and operate at different voltage
ranges. Top rows of batteries in multiple-tier configurations
tend to operate at slightly higher temperature than those
on lower tiers. Always provide adequate ceiling clearance
for ventilation and maintenance.
Anchoring: To provide stability, safety, and seismic integrity,
racks must be securely anchored to the floor. Anchor bolts
are to be installed per vendor’s specifications and in
accordance with applicable codes. Do not attach rack to
walls without consulting C&D first. Mounting holes are
provided in the base of each frame. All frames must be
secured to floor using all anchor locations. It is the
responsibility of the customer to secure racks in
accordance with allowable floor loading, applicable
codes and regulations.
Grounding: Rack grounding provisions are integrated into
the base of each frame. Two 7/16” (11mm) diameter thru holes
are located at the center of the frame's bottom cross member
and may be used to secure a standard NEMA lug. These
two holes have 1.0” (2.54cm) between centers and have
been masked and are free of powder coating to allow for
electrical contact. Frame to frame grounding integrity is
accomplished via the lower support rail, attached to
each frame with an Internal/External “star” washer.
NOTE:
Floor mounting hardware is to be determined in
accordance with applicable building codes, not by
C&D. For proper certification, a floor anchor must
be a minimum or equivalent to an Hilti HSLM12-25.
CAUTION:
Do not install batteries until the rack has been properly
installed, with all bolts tightened to specified torque and
frames anchored to the floor.
Do not use oil, grease or any other lubricating agent as a
lubricant for cell installation. This could void the warranty.
Lubrication is usually not required due to the low friction
interface of the insulated covers. If necessary, a small
amount of water or unscented talcum powder can be
applied to the rail covers to reduce friction.
