The key switch must only energize a relay as described above.

  • Page 13: Remote Control Head Location

    D) The Actuator is usually located in the engine room. If the engine room is too small, locate in any accessible area. E) MicroCommander uses electronic circuits that can be influenced by strong magnetic fields, and static charges. Power source must be bonded (connected) to the hull. Do not mount close to gas engine ignition systems, alternators, or electric motors.

  • Page 14: Dc Power Source

    Mathers Controls Inc. D) Retrofit applications will need to plan an adapter pad to cover the old control cutout and to mount the control head. Adapter and cover pads are available from Mathers Controls Inc. 3.3 DC POWER SOURCE The MicroCommander Actuator requires a battery source (12, 24 or 32 volts DC) protected by a 10 ampere circuit breaker.
