Leveling:

With all support rails (not all side) rails and covers in place, the rack needs to be checked for level

and square. Shim frames as necessary to obtain level and squareness. Shims are not supplied by C&D.
With all frames level and square, torque cross brace bolts then torque the support rail to frame bolts.
Torque anchor bolts to manufacturer’s recommended value.

Install Inward Bracket of Battery Restraint Brackets:

Install partially assembled battery bracket in approximate
location with hardware loose, so bracket may slide into
exact location at a later step in the installation. This
bracket may not be required, depending on the rack
drawings. See Figure #7 and Detail #4.

IMPORTANT STEP:

Place front restraint rail and cover on frame cross member (top and bottom rows) to be installed after all batteries

are in place. These rails should be slid up into position rather than dropped down from the top.

Cell Installation Procedure:

If not instructed otherwise, install cells starting at the center of the bottom row

and working out to each end, install cell foam battery spacers as supplied if indicated by drawings.

Battery Restraint Bracket Assembly:

Install the

tie rods and covers of the battery restraint bracket
assembly. See Detail #4. If batteries are completely
installed before this step, installing tie rods and
covers will be very difficult.

Cell Installation Procedure Continued:

Do not use

oil, grease or any other lubricating agent, as a lubricant
for sliding batteries into place. Use a small amount
of water or unscented talcum powder to help reduce
friction on rail cover. Pay close attention to the
polarities and terminal placement. Refer to the
battery’s Installation and Operating Instructions
Manual for more details. All cells should be pushed
back against the back restraint rail and cover.
Repeat this procedure for all remaining rows and
tiers. Completely finish the bottom row before
starting the top row.
