Module Stacking/System Assembly
With base properly installed, modules
unpackaged and in the horizontal position,
locate the C&D issued system diagram to
verify proper cell orientation when stacking
modules.
C&D recommends the following two methods for
handling Liberty 2V modules.
1. Portable Crane/Fork lift:
In the case of limited access in the rear of the
module install only the (4) 10mm bolts in the
rear flanges prior to hoisting. Connect optional
lifting straps in a “X” pattern as shown and
hoist carefully.
Note: Depending on the battery type some
sagging may occur while lifting however once
released and in position will return to square
(See Figure A9).
2. Battery Lift Table:
Again prior to hoisting, install only the (4)
10mm bolts in the rear flanges. Verify module
orientation then position module on lift table
keeping metal surfaces isolated from battery
terminals. The modules flat top and bottom
surfaces allow it to easily slide from the lift
platform to the base with little effort (See
Figure A10).
Note: When lifting battery modules always
verify the lifting capacity of the equipment
being used and never lift more than one
module at a time.
3. Next, make only the lower tier module to base
connections using (8) 10mm bolts (4/side).
Torque to 40 ft-lb [55N*m].
Note: Only the Module – to – Base connection
requires the use of all (8) bolt connections
(See Figure A11).
