STANDBY BATTERY RACKS
ASSEMBLY INSTRUCTIONS
Applies to All rdb series pAcks
(reAd All instructions prior to instAllAtion)
These instructions detail the proper procedure for installing C&D
Standard and EP (Earthquake Protected) battery racks. The following
describes how to locate, assemble, and load open-frame battery
racks for C &D battery mounting applications. Proper attention to
these instructions will help ensure safe, trouble-free performance.

Figure 1. Standard Vs. EP Rack
Standard and Earthquake-Protected (EP) Racks:
Earthquake-protected racks are similar to standard racks, with
the exception of additional frame bracing, battery constraints and
spacer elements. Frames are the same for both Standard and EP
series. EP racks are certified to Section 1630 of the Uniform Building
Code, 1994 edition. See Figure 1.
Configuration:
Racks are available in single or multiple tier/step arrangements as
shown in Figure 2. Rack components are supplied loose and must
be assembled and secured on-site in accordance with these C&D
assembly instructions, the drawings included with the rack shipment,
and applicable codes.
Rack Location:
Locate racks in a clean, cool, dry place so the batteries are not affected
by sources of radiant heat, such as sunshine, heating units, radiators,
steam pipes, etc. Variations of more than 5 degrees F between cells
may cause the battery to become electrically unbalanced. 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 (for EP series),
racks must be securely anchored to the floor. Anchor bolts are to
be installed per contractor 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 bolt 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 through holes are located at the center of the frame’s
bottom cross member and may be used to secure a standard NEMA
lug. These holes are 0.44” in diameter and 1.0” between centers.
The surfaces surrounding the holes have been masked and are free
of powder coat to allow electrical contact. Frame to frame grounding
integrity is accomplished via the lower support rail, attached to each
frame with Internal/External “star” washers.

Lubrication is usually not required due to the low friction
interface of the insulating covers. If necessary, a small
amount of water or unscented talcum can be applied to
the rail covers to reduce friction.
Assembly InstructIons for
stAndArd And eP rAcks
1 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 on provided drawings and /or
packing list. Do not assemble rack if parts are missing or
quantities are incomplete.
2 Required Tools : Torque wrench (0 to 65 ft.-lb.) with 9/16”
and 3/4” Hex socket. Adjustable wrench or 9/16” and 3/4” box
wrenches, tape measure, square and leveling device.
Note: Consult manufacturer’s instructions for tools required to
install floor mounting hardware.

Existing Boundary
3 Location of Rack Assembly: When determining rack
location and floor bolt pat tern, use applicable drawings
provided with rack shipment. Locate the rack’s general position,
considering boundar y and aisle clearances. Locate floor
mounting locations using provided drawings. See Figure 3.
Note: Floor mounting hardware is to be determined in
accordance with applicable building codes, not by C& D.
4 Initial Assembly: Place frames over installed floor
mounting hardware, finger tight. (Hardware not supplied by
C&D). All frames must face the same direction. Install back
cross braces, finger tight. See Figure 4. Do not install front
cross braces at this time (if required).
Note: Cross bracing pattern along the length of the rack
may not necessarily be symmetric. Cross bracing pattern
and location(front, middle, or back) is detailed on assembly
drawing provided with the racks.
