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.
