2.4.2 How to connect the cables
Three cables are connected to the Antenna Unit: antenna, sub monitor* and de-icer*
power cables (*: option). The procedure shows how to connect all cables. Disregard
the descriptions for the optional equipment if not applicable.
Note: Apply the supplied adhesive to the unused cable glands.
1. Loosen four bolts on the rear cover to remove the rear cover. If the de-icer is al-
ready installed, loosen also four bolts on the front cover to remove the front cover.
If the lifting fixtures are still attached, they should be removed. For how to remove
the lifting fixtures, see section .
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, remove two M5 screws and spread open
the right and left heater elements on the cover, then remove the front cover, being
careful not to hit the elements on the radiator or chassis.
