C&D Technologies RS-1476 Standby Battery Vented Cell - Manual (Page 8)

3.1 Installation of Battery Rack(s), Overview
NOTE: Standby Battery Rack assembly instructions and/or rack assembly drawings are supplied with
C&D supplied racks and should be consulted for detailed instructions specific to your rack assembly
prior to assembly.
Remember that standby battery and rack systems will be in place for many years. Rack frames, rear
cross bracing, bottom and rear support rails are assembled before any batteries are installed.
CAUTION
Racks must be installed in a safe location for maintenance and away from radiant heat sources. Before
batteries are installed, racks must be level and have cross braces in place. All bolts must be tightened
to specified torque values. Floor loading must be considered in the planning phase.
1. For C&D Technologies supplied racks, follow the instructions in the rack assembly instruction guides and/or the
C&D Rack Assembly drawing – supplied with the rack - to mark the rack footprint, rack frame locations with spacing
and anchor bolt locations and drill holes for the anchor bolts.
2. Follow the instructions as noted for initial assembly steps including mounting the frames to a flat and even floor
with anchor bolts and attaching the rear cross bracing. Hand tighten all the bolts and nuts.
3. After ensuring that all the frames are plumb, vertical and level, tighten all bolts and nuts to the specified torque
value starting with the rear cross braces and then the support rail clamp nuts. The anchor bolts are to be tightened
to the manufacturer’s recommended torque value.
4. For seismic racks, position rear restraining rails and tighten bolts and nuts to the proper torque. Temporarily
position the front restraint rail and cover down next to the front support rail prior to installing the cells.
5. Install plastic rail covers prior to installing batteries.
6. Front and end restraining rails are usually installed after the cells have been placed on the rack. Installation of
the front restraint rails after the cells are in place can be completed by simply raising the restraint rail into position.
A gap between the battery jar walls and the rails of the approximate thickness of a credit card is typical.
7. The end restraint rails and corner brackets are to be installed and moved up to the end batteries of the tier.
8. Secure rack assembly checking that all bolts and nuts - including anchor bolts - are tightened to the proper
torque.
NOTE: Anchor bolts are not selected or supplied by C&D Technologies, Inc. but are the responsibility of the
installer. Installation must be in accordance with local building code requirements.
CAUTION
• Top rows of batteries in multiple-tier installations tend to operate at slightly higher temperatures
than those on lower rows. Always provide adequate overhead (minimum of 8” to 12” recommended)
clearance for ventilation and maintenance.
• When assembled, battery racks must be anchored to the floor.
• Do not place battery cells on the rack until it has been completely assembled with the braces
installed, secured to the floor and all bolts tightened to specified torque (refer to sequential steps of
rack assembly). Otherwise, the weight of the cells may cause the rack to shift and collapse.
• Never loosen or remove braces from a standard loaded battery rack. Removal of bracing can allow
the rack to shift and collapse. Front restraining rails on seismic (EP) racks may be removed to
accommodate loading/unloading of cells.
NOTE: It is helpful to clean the rack(s) and the area surrounding the installation to remove abrasive
materials and residual building materials before installing cells. This will not only reduce the chance
of damaging cell containers but will ease installation and simplify final cleaning of the assembled
battery.
