“L” SERIES NEBS COMPLIANT
STANDBY BATTERY RACKS
ASSEMBLY INSTRUCTIONS
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.

MATERIAL VERIFICATION
Battery racks are shipped unassembled with a complete
set of related drawings and documentation. Check received
parts and quantities against the rack’s Bill of Materials
(reference Table #1) on the provided drawing or packing list.
Do not assemble rack if parts are missing or quantities are
incomplete. Please contact C&D’s customer service,
800-543-8630 with any problems.
REQUIRED TOOLS
Torque wrench (0 to 120 ft.-lb.) with hex sockets for 3/8”
and 1/2” hardware. Adjustable wrench or 3/8” and 1/2” box
wrench, tape measure, square and leveling device.
Note: Consult manufacturers’ instructions for tools
required to install floor anchoring hardware.
INSTALLATION DETAILS
Bolted connection details are located at the end of
installation manual for reference. Torque values for
hardware are shown in Table #2.
LOCATION OF RACK
When determining the rack location and floor anchor pattern,
use applicable drawings provided with rack shipment.
Locate the racks’ general position, considering boundary
and aisle clearances. Locate floor anchoring locations
using provided drawings.

ASSEMBLY INSTRUCTIONS:
1 Initial Assembly: Place frames over installed floor mounting hardware, finger tighten. See Figure #3. (Floor anchors are
not supplied with rack) All frames must be in the proper orientation as shown on the rack assembly drawing. Install back
(away from aisle) cross braces for single row rack and center braces for double row rack. See Figure #4. Please refer to
rack drawing for proper orientation of cross braces. Refer to Detail #1 for brace to frame installation and Detail #3 for
brace to brace connections.

FIGURE #4 Installing Cross Braces.
Place support rail(s) in location using supplied 3/8” bolt, lock washer and serrated strut nut. Ensure that the strut nut has
properly engaged the strut.
Side Rails: Install back side restraint rail for 2-tier racks and center side rails on 2-tier/2-row racks.

See Figure #5. Refer to Detail #2.
3 Installing Support Rails: Install support rails from the back to front on 2-tier racks and from the center outward
on 2-tier/2-row racks. See Figure #6.
