1.3 Slip Ring/Rotary Joint Assembly Description
The SLIP RING/ROTARY JOINT ASSEMBLY includes a Slip Ring and a Rotary Joint.
The Slip Ring is used to pass the following:
AC power from the ADE POWER BOX to the power supply modules
DC power from the ACU to the IMU.
Communication between the ACU to the IMU.
The Rotary Joint is used to pass the following, between the ADE POWER BOX and the ADMX:
Tx and Rx signals
10 MHz reference signal
LAN communication
Figure 1-1: Slip Ring/Rotary Joint Assembly
The SLIP RING/ROTARY JOINT ASSEMBLIES have the same mechanical interface and
different electrical interfaces.

2Preliminary Procedures
To Perform Preliminary Procedures:
The preliminary procedure described below must be performed before replacing the
SLIP RING/ROTARY JOINT ASSEMBLY:
1. Perform System Shut-Down of the vessel’s main power AC Voltage terminal outside the
RADOME.
2. Open the RADOME hatch.
3. Switch off the ADE POWER BOX at the ANTENNA PEDESTAL base (located inside the
RADOME).
4. Manually rotate the PEDESTAL AXES to gain convenient access to the serviced unit.
In the following procedures, be very careful when tightening and loosening the
screws with which the parts are assembled and attached to the system. Some
of these screws are delicate and can be damaged by excess force. When
using an Allen key make sure to insert the key all the way into the screw head
to avoid thread stripping.
WARNING!
The Utility Outlet is connected directly to the vessel’s AC voltage input
terminals (125 VAC / 250 VAC). Therefore, there still exists live voltage at the
Utility Outlet after disconnecting the power supply to the ADE using the Mains
Power On/Off Switch.
Only qualified and authorized personnel are allowed to carry out system
service/maintenance procedures.
