Electrical resistance in a circuit is the consumer of the electrical energy. When installing a
KAPower Module, keep resistance to a minimum. Short, heavy cables, and clean cable
connections are essential to reducing the amount of resistance in a circuit.
When selecting a location for installation, make sure that the KAPower KSM module will clear
any lids and other movable parts. Install the KAPower KSM module as close to the engine's
starting batteries or starter as possible. Avoid locations that are subject to extreme heat,
humidity, dripping water (under deck ventilation systems aboard boats, for example), road
dirt, ice, and snow. Prevent the external case of the KAPower KSM module from physical
impacts.
4.1 Electrical Cable Selection
1.
Electrical resistance in a circuit is a significant consumer of the power available in the
KAPower device. Create and keep the integrity of the circuit to the highest possible
standards.
2.
Use the heaviest gauge cable available. For 24-volt (and 10 cell units), use at least
2/0, with 4/0 being recommended. A six cell, 12-volt unit may use 4 gauge to 2/0
cables.
3.
Keep cable length to an absolute minimum. The circuit resistance increases with cable
length.
4.
Ensure that the cable termination connections (terminals) are properly crimped, and
ensure that the holes in ring terminals match the size of the studs over which they are
placed. Do not use welding cable; use high quality, fine strand type II or type III
battery cable. Marine applications should utilize tinned cable and dielectric grease.
5.
The quality of the cable connections from the KSM to the vehicle’s or vessel’s
battery/starter circuit, or equipment, is critical. Make sure to provide good, clean,
robust cable interface connections. The cables between the KSM module and the
battery are cranking motor conductors, and therefore are typically not equipped with a
fuse or circuit breaker. If a short circuit occurs, the cable will overheat, and it may
catch fire, or ignite nearby combustible materials. Therefore, make certain the cable is
well-secured, at least every 18-inches, and protected from damage and chafe. For
marine installations, follow American Boat and Yacht Council Guidelines found in
chapter E-11 (not included in this document).
