TEC32-1664-009 OceanTRx7™ ADMx Technical Note Page 4 of 10
2 Preliminary Procedures
The preliminary procedures described below must be performed before replacing the ADMX.
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.
