Power Connections

The power connections are M6 diameter threaded posts. The wire used should
be of a diameter appropriate for the load envisaged.
Battery Wiring
Keep the battery wiring as short as possible to reduce the load on the main
capacitors.
Motor Wiring
To reduce electrical noise the motor wires should be kept close to each other and
twisted together if possible. A 10nF 100V disc ceramic motor suppression
capacitor should be fitted across the brushes of the motor. Ferrite rings should be
fitted on the motor wires. See the knowledgebase on our website for more
information on noise suppression.
If the motor rotates in the wrong direction, swap over the M+ and M- wires.
Battery Circuit Breaker
A circuit breaker or fuse should be fitted in the battery wiring. The rating should
be above that of the motors normal operating current.
A battery isolator switch should also be fitted to provide an emergency
disconnection capability. In some applications such an isolator is a legal
requirement.
Failsafe
The Pro-160 has provision to drive a failsafe contactor which can provide an
emergency disconnection in the event of a controller failure. Details of how to
implement this feature are on our website.
