Trim the armor so that it does not extend past the flat washers. Gasket Push the flat washer against the armor. 7. Pass the serial cable through the cable entrance. If applicable, unfasten the appropriate cable gland and pass the de-icer power cable through the cable entrance. Pass the cable through appropriate locking wire saddle. 8.
2. WIRING 10. DE-ICER INSTALLATION. See “De-icer Kit Installation Instructions” (for TRDOWN radar, C32-01406), issued separately, for the de-icer not fitted at the factory. If the de-icer is not provided, go to step 12. [TEST] button Voltage Setting switch Front cover w/de-icer, inside view TB901 DEICER Board (03P9573) 1) Remove four bolts then spread open the right and left heater elements on the front cover.
2. WIRING 5) Unfasten the cable band* on the front cover. Pass the de-icer power cable through the band then fasten the band. Connect the cable to TB901 on the DE-ICER board (03P9573), using the supplied crimp-on lugs. *: For the DE-ICER installation kit, unfasten the cable band on the cover supplied with the kit. (The original cover can be discarded.) 6) Set the Voltage Setting switch according to the power source for the de-icer; 115 V or 230 V. The default setting is 230 V.
