VRLA RB BATTERY RACKS
ASSEMBLY INSTRUCTIONS
(READ ALL INSTRUCTIONS PRIOR TO INSTALLATION)
For All Standard And Seismic Models Including Retrofitting
Standard Models To Meet Seismic Requirements
Safety
Installation of VRLA batteries should only be performed and supervised by trained personnel knowledgeable of lead
acid batteries and the required personal and equipment safety precautions. Keep unauthorized personnel away from
the batteries and assembly activity.
Observe battery safety procedures. Use insulated tools, gloves, safety glasses, and remove all jewelry etc..
Special care should always be taken to avoid short circuiting any battery connection.
Wash hands after any contact with lead or electrolyte.
Rack Configurations
Racks are available in single or multiple tiers. Rack components must be assembled and secured on-site in
accordance with these C&D assembly instructions, rack drawings and applicable codes. Because EQ Racks meet
Seismic requirements, they may NOT be mechanically secured together.
A minimum distance of 3” must be allowed between racks and between racks and the building structure.

Tools for RB Rack Assembly
The following items will assist you to properly assemble rack materials. Insulated tools are strongly recommended
for safety purposes.
9/16” socket wrench Torque wrench to 46ft-lbs Tape measure
9/16” open-end wrench Needle nose pliers Knife
Chalk and line to mark floor Bubble level Square
Power drop cord Drill & concrete bit (for floor anchors)
Required Materials Supplied by Installer
Seismic Qualified floor anchor bolts (4 per rack)
1/8” thick (X) 2 3/8” wide (X) 3 3/8” long metal shims with 15/16” centered cutout (length wise).
Quantity of shims depends on floor surface.
Rack Location
Locate racks in a clean, cool, dry environment to avoid exposing the batteries to sources of radiant heat, such as
sunshine, heating units, radiators, and steam pipes etc. Top rows of batteries in multiple-tier configurations tend to
operate at a slightly higher temperature than batteries on lower tiers. Always provide adequate ceiling clearance for
ventilation and maintenance.

Anchoring
Seismic racks must be securely anchored to the floor and in accordance with applicable codes and regulations. Four
15/16” diameter mounting holes are provided in the rack base. Seismic racks must be secured to the floor using ALL
anchor bolt locations.
Anchor mounting hardware must be capable of withstanding foundation allowable loads of 4,000-lbs. pullout and 576lbs. shear. Anchor spacing based upon the mounting holes in the RB Rack is 12.5”. You must allow a minimum of 3”
between racks and between racks and the building structure to allow for drift.
To properly select anchoring system hardware, the concrete floor strength in psi must be
determined.
Grounding
Each rack has grounding strap provisions. Two 15/32” diameter mounting holes are located on each vertical frame
and accept single hole or dual hole lugs on 1” centers. The surfaces surrounding the holes are free of powder coat to
allow electrical contact.
Standard and Seismic Rack Comparison
EQ series Seismic Zone 4 racks are similar to standard racks, but with the addition of hold down struts, battery end
brackets, spacers, and covers for Seismic racks. Frames are the same for both Standard and EQ series racks. EQ
series Seismic racks are certified to the 1997 Uniform Building Code.

1. Receive and inspect rack components
Upon receipt of the RB Rack materials, inspect and document any damage to these materials.
Damage claims must be filed promptly with the carrier.
2. Review drawings and instructions
3. Verify Parts Received Against Bill of Materials
Standard RB Series Rack components are shipped in 2 boxes. If an optional cover was ordered, there will be one
additional box.
Seismic RB Series Racks are shipped in 3 boxes plus one additional box for each tier.
Before assembly, verify that all rack materials are present against the detailed bill of materials shown on the RB
Rack Assembly Drawing (RB_ _T) or (RB_ _TEQ).
4. Obtain installer supplies (listed on page 2)
5. Get safety equipment and tools (listed on page 2) to rack installation location
