2.2.2 How to connect the cables
If there is a chance of inclement
weather when the RF unit is
removed, cover the intakes on both
covers with packing tape for
waterproofing. Be sure to remove the
tape after completing the installation.
Some parts or wiring have been omitted from the illustrations for clarity. Also, in the
procedure, mainly figures of magnetron radar are shown.
1. Unfasten four bolts from the rear cover to remove the rear cover. If the de-icer is
already installed or will be installed, remove two bolts inside the antenna to re-
move the front cover.
Note 1: The cable for the performance monitor is connected between the rear
cover and the RF-TB Board in the antenna unit. Open the cover slowly to prevent
damage to the cable and connector.
Note 2: If the de-icer is to be installed, spread open the right and left heater ele-
ments on the cover, then remove the front cover, being careful not to hit the ele-
ments on the radiator or chassis.
Note 3: If this a retrofit or foremast installation, a LAN Signal Converter is re-
quired, in both the antenna unit and the power supply unit. See section 2.7.
