The unit has 4 screw holes for mounting, and should be placed as
near the Control Unit as practical. It can also be mounted inside a
console.

Electrical connections

General

The standard mains supply is 24 VDC. For AC mains
connection an AC adapter rated at 24VDC 1,5A must be
connected between the mains source and the distribution unit
(not standard scope of supply).
Depending on type of distribution unit, the solid state relays are
capable of operating solenoids for high and low DC or AC.
Analog voltage or current output is also available for steering
gears that require analog input signals.
Grounding and Radio Frequency Interface (RFI)
The AP50 system has excellent Radio Frequency Interference
(RFI) protection and all units use the distribution unit as a
common ground/shield connection. The distribution unit has an
external ground terminal and must have a proper ground
connection to ships hull. The grounding wire should be as short
as possible and at least 10 mm wide (screen from coax cable or
similar).
Robnet cables and other signal cables (i.e. compass, feedback,
NMEA) should not be run in parallel with other cables carrying
radio frequency or high current, such as VHF and SSB
transmitters, battery chargers/generators, and winches.

The plug-in terminals are located at the bottom of the cabinet.
Insert the cable through an appropriate cable gland. Strip of the
cable insulation. Provide sufficient wire length so that the plug-
in terminals can be easily connected and disconnected.
