7.5 Preparing and Installing Connections, continued
7.5.2 Intercell Connectors
The connections are made by bolting the fl exible copper intercell connectors to
the cell posts of opposite polarity on adjacent cells. When more than one intercell
connector per cell is furnished, bolt the connectors on opposite sides of the cell
posts. See the assembly drawing, included with the shipment, for details.
Clean the contact surface of the intercell connector using a stiff bristle
nonmetallic brush/pad.
With a small paintbrush, apply a light coat of ARONIX grease to the contact
surface of the intercell connector.
Bolt all intercell connectors according to the assembly drawing.
Secure all connections fi nger-tight to allow for some adjustment of position.
After all connections are completed, torque all stainless steel connector bolts
132-177 inch lbs (15-20 Nm). Make sure that all bolted battery connections
are torqued to the recommended values. The increased resistance of a loose
connection can generate heat and become a fi re hazard.
Apply a light coat of ARONIX grease to the bolted connection with a small
paintbrush in the area of the terminal post only.
7.5.3 Terminal Plates
If terminal plates are supplied with the battery system to provide a system connection
point. All system connections must be made to the terminal plate and never to the cell
terminal post.
Clean the electrical contact areas of the terminal plate, terminal connectors, and
cell/jar posts with a stiff-bristle nonmetallic brush or pad until the surface is bright.
With a small paintbrush, apply a light coating of ARONIX grease to contact areas.
Install terminal connectors to cell posts. Tighten connections to 132-177-inch lbs
(15-20 Nm).
With a small paintbrush, apply a light coat of ARONIX grease to the electrical
contact areas of the terminal plate.
Install the terminal plate to the terminal connectors again using the torque values
of 132-177 inch lbs (15-20 Nm).
Connect the positive lead from the charger to the positive terminal plate of the
battery and the negative lead from the charger to the negative terminal plate of
the battery (Some seismic installations have interface connections).
Connectors to battery terminal plates should be fl exible, since rigid terminal
connectors may transmit vibrations or strain to cell posts that could result in loose
connections. Support cables so that the cell post does not bear the load.
