Final check
After installation, the cable glands must be sealed with silicon to
prevent water from seeping in. Also apply silicon grease to the
gasket between the bottom and top cover.
On the inside of the feedback unit cover, a piece of moisture
protecting sponge is attached. The sponge produces a corrosion
preventive gas, and to increase the efficiency of the gas the
cover must be kept tight.
2.9 J50 Junction Unit
The J50 Junction Unit is designed to operate in a location that
provides ambient temperatures below +55°C (+130°F).
Note ! The junction units (J50 and J50-40) are not waterproof and
should be mounted vertically, as shown in Figure 2-11, 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 Unit 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.
