Securing Cable Connections
Installation Environment
Please secure all cable connections to the proper specification in order to ensure good
contact between the cable lugs and the terminals. Over-tightening cable connections can
cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
To ensure good contact between the cable lugs and the terminals, please use the
appropriate number of washers to allow for as much thread engagement as possible
without bottoming out the terminal bolt. The correct number of washers can be
determined by hand-tightening the terminal bolt with just the cable lug in place and
observing the gap that is present. Use the number of washers needed so that the
washer stack is slightly larger than the observed gap.
The battery should be installed in a clean, cool, and dry place, keeping water, oil, and dirt
away from the battery. The accumulation of these materials on the battery can cause current
leakage, resulting in self-discharge and a possible short-circuit. Sufficient air flow must be
provided to prevent excessive heat build-up and to minimize temperature variation between
the batteries.
It is important to ensure that the cable lug and the top surface of the terminal are in contact.
The washer(s) must be placed on top of the lug. Do not place the washer(s) between the
battery terminal and the cable lug as this can cause high resistance and excessive heating.
Please use an insulated Philips screwdriver to tighten the cable connections.
Please use the included Long Terminal Bolts when needed to secure multiple cable lugs on
a single battery terminal.
