2 — HARDWARE INSTALLATION

Keyswitch

The vehicle should have a master on/off switch to turn the system off

when not in use. A keyswitch is typically used for this purpose.

Polarity Protection Diode

For polarity protection, a diode should be added to the control circuit.

This diode must be sized appropriately for the maximum total contactor

coil currents.

Control Wiring Fuse

To protect the control circuitry from accidental shorts, a small fuse

(typically 10 amps) connected in series with the B+ feed to the control

circuitry wiring is recommended.

Power Wiring Fuse

To protect the power wiring circuit, a fuse appropriate for the controller’s

rated current (see Appendix D) is recommended.
