Connecting To Power Supply; Pilot Plug Connection - mcmurdo SmartFind M6 AIS CLASS A Installation Manual

2.10 Connecting to Power Supply

The M6 requires a switched 12 V or 24 V DC power supply (9.6 to 31.2 V operation
range) capable of supplying 4 A peak current. The red wire and the black wire on the
3-pin cable are used to connect the power supply's positive and negative terminals. A
switched 4 Amp fuse or circuit breaker must be used in the connection between the
power supply and the unit.
M6 will turn on and start operating as soon as the DC power is applied.
Use the remote isolation switch if it's required to turn off the M6.

2.11 Pilot Plug Connection

The M6 has an integrated pilot plug on the front panel with the IMO standard AMP
connector. Open the waterproof lid to connect the PPU (Personal Pilot Unit). When
needed, an optional pilot plug is available for purchase to be connected through the
junction box.
It is recommended to keep the pilot plug lid closed when not in use.
