Electrical System
Functional Description
The electrical system consists of switches, circuit breakers, and contactors mounted inside the control housing,
and inside the battery compartment. The battery charger is a "shelf" style charger which is 36 volts DC, and has
an output of 25 amps maximum.
The electrical system is powered by (6) 6-volt batteries for a total of 36 volts. Heavy cables connect the batteries
in series. A large gray main battery pack connector is used for connecting the batteries to the "shelf" battery
charger unit.
The control system will turn off the scrub system and recovery systems if the battery voltage drops too low to
prevent damage to the batteries due to excessive discharging.
The circuit breakers protect various circuits from excessive current.
