BATTERY SYSTEM
The battery connectors shall be heavy duty type with cables terminating in heat shrink loom. Heavy duty battery
cables shall provide maximum power to the electrical system. Where required, the cables shall be shielded from
exhaust tubing and the muffler. Large rubber grommets shall be provided where cables enter the battery
compartment.
Batteries shall be of the high-cycle type. With the engine off, the battery system shall be able to provide the
minimum continuous electrical load for 10 minutes without discharging more than 50 percent of the reserve
capacity and then to restart the engine. The battery system cold cranking amps (CCA) rating shall meet or exceed
the minimum CCA recommendations of the engine manufacturer. The batteries shall be mounted to prevent
movement during fire apparatus operation and shall be protected against accumulations of road spray, snow, and
road debris. The batteries shall be readily accessible for examination, testing, and maintenance.
A means shall be provided for jump-starting the engine if the batteries are not accessible without lifting the cab of
a tilt-cab apparatus.
Where an enclosed battery compartment is provided, it shall be ventilated to the exterior to prevent the buildup of
heat and explosive fumes. The batteries shall be protected against vibration and temperatures that exceed the
battery manufacturer’s recommendation.
A master load disconnect switch shall be provided between the starter solenoid(s) and the remainder of the
electrical loads on the apparatus. The starter solenoids shall be connected directly to the batteries.
Electronic control systems and similar devices shall be permitted to be otherwise connected if so specified by
their manufacturer.
The alternator shall be wired directly to the batteries through the ammeter shunt(s), if one is provided, and not
through the master load disconnect switch.
A green “battery on” pilot light that is visible from the driver’s position shall be provided.
A sequential switching device shall be permitted to energize the optical warning devices and other high current
devices required in minimum continuous electrical load, provided the switching device shall first energize the
electrical devices required in minimum continuous electrical load within 5 seconds.
BATTERY SWITCH
One (1) battery "On/Off" switch in cab located within easy reach of Driver with green "BATTERY ON" pilot light
that is visible from the driver’s position shall be provided.
BATTERY SOLENOID
Battery switch shall consist of a minimum 200 ampere, constant duty solenoid to feed from positive side of
battery.
SHORE POWER INLET
One (1) Kussmaul 120 VAC, 20 amp shore power inlet with weather resistant snap cover shall be provided. The
protective ground from the shoreline inlet shall be bonded to the vehicle frame.
• The outlet cover shall be yellow.
• The shore power plug shall be located near the Driver door area.
