4.8 Junction unit
The junction unit is designed to operate in a location that provides ambient
temperatures below +55°C (+130°F).
Note ! The junction units (J3000X, J300X and J300X-40) are not water proof and
should be mounted vertically as shown in a dry place between the control
unit and the drive unit.

Cable connections
Use only shielded cables. This includes Mains input, drive units and if
necessary for the extension of the RF300 Rudder Feedback cable. The
clutch/bypass cable and the solenoid cable should be 1,5 mm
2
(AWG14).
Signal cables should be 0.5 mm
2
(AWG20) twisted pairs.
The mains supply cable and the drive unit motor cable should have sufficient
wire gauge. This will minimize voltage drop and allow the drive unit to
operate at full power.
Refer to the table below for recommended cable sizes.
