Connecting And Torquing Battery Terminal Posts - C&D Technologies LIBERTY 1000 Series Installation And Operating Instructions Manual

Do not use steel brushes, steel wool, sandpaper or emery cloth
to clean surfaces, as these will damage the plating. Do not use
cleaning solvents. Solvents can cause crazing or cracking of
the plastic cell containers or covers. Use of solvents will void
the warranty.
4. Attach intercell connectors or cable/lugs from the positive post of
one unit to the negative post of the next cell or unit for series
connection. If the units are mounted on more than one tier make
certain to follow the polarity convention, positive post to negative
post. Inter-tier and inter-row connections are typically made with
cables with lugs on both ends. Do Not Use Steel or Cadmium
Plated Lugs.
5. Large batteries may use "Terminal Plates" to accommodate
multiple cable connections. There are a variety of optional terminal
plates available from C&D Technologies, Inc., Inc. Terminal plates
should be clean and prepared in the same manner as the intercell
connectors.
4.2 Polarity of assembled units/cells and inter-row, inter-tier
connections
Cell/unit polarities have been marked by a raised mark in the covers to
provide proper interconnection between cells. When connecting
cells/units be sure that all terminals, including inter-tier, have been
connected positive (+) to negative (-) from one cell/unit to another
throughout the battery.

4.3 Connecting and torquing battery terminal posts

Liberty Series 1000 batteries are available in various sizes and volt-
ages as described in Table 2 and with corresponding Ampere-hour
ratings at the 8 hour rate of discharge: 80 Ah, 100 Ah, 125 Ah, 200
Ah, 300 Ah, and 600 Ah. The units are connected positive to negative
from one unit to another unit in a series arrangement. This is accom-
plished by fastening the tin plated connector (used on larger size
units) or lugs found on cables (for smaller size units) from the positive
terminal of a unit to the negative terminal of the next unit. The lug or
connector is secured with the appropriate terminal hardware
described in Table 2 and tightened to the torque value specified in
Table 2.
Connect cells/units with the stainless steel hex head bolts and
washers in accordance with the connecting instructions for the
system. Torque all connections to the proper torque value shown in
Table 2.
It is recommended that the top tier of connectors be installed first on
multi-tier racks, then the second and so on, working from the top
down. This may avoid short circuiting connected groups of units in
lower tiers.
