2.5.1 How to fabricate the cables
For how to connect the WAGO connector, see "WAGO connector" on page 2-6.
TTYCYSLA-10 (for serial cable)
DPYCY-1.5 (for the optional de-icer)
• Before beginning any work on the Antenna Unit, turn off the breaker for the de-icer
at the mains switchboard. (Turning off the display unit has no effect.)
• The neck of the Antenna Unit becomes VERY HOT when the de-icer is working.
(The de-icer turns on when ambient temperature goes down to 5°C and heats to
55°C.)
Wrap the spiral tubing near the crimp-on lugs.
Microwave coaxial cable
See the supplied instruction manual (C32-01904) in Antenna Unit for details.
2.5.2 How to connect the cables for S-band (TR-DOWN) radar

microwave coaxial cable and de-icer power cable (option). The procedure shows how
to connect all cables. Disregard the descriptions for the optional equipment if not ap-
plicable.
Note: Apply the supplied adhesive to the unused cable glands.
