STANDBY BATTERY RACK
ASSEMBLY INSTRUCTIONS
APPLIES TO ALL RDC SERIES RACKS
(READ ALL INSTRUCTIONS PRIOR TO INSTALLATION)
Standard and Earthquake-Protected (EP) Racks:
Earthquake-protected racks are similar to standard racks,
with the exception of additional frame bracing, battery restraints,
and cell spacer elements. The battery rack frames are common for
Standard, EP1 and EP2 series for the one-tier, two-tier, three-tier
and two-step racks with the exception of the three-tier EP2 rack.
The frame for the three-tier EP2 rack is unique. RDC-EP racks are
certified to the International Building Code, 2009 edition.
Configuration:
Racks are available in single or multiple tier/step configurations 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 Fahrenheit (3º C)
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 and safety, 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 the appropriate structural
engineer. Mounting holes are provided in the base of each frame.
All frames must be secured to floor using all anchor bolt hole
locations.
• 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 or grease as a lubricant for cell installation.
Lubrication is usually not required due to the low friction
interface of the insulating covers. If necessary, a small
amount of water, unscented talcum or Dow Corning III can
be applied to the rail covers to reduce friction.
CAUTION:
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.
