Connect the ground wire to the crimp assembled under the screw. The wiring of the AC (mains) input to the X1 connector is instructed in Figure 4 on page 11. Refer to Figure 5 below for the location of the connectors and cable glands on the WHP25 unit. 7. Tighten the input cable glands.
Chapter 3 __________________________________________________ Installation 8. CAUTION Enter the output power cable(s) through the rightmost cable gland(s). For better protection against RF interference, ground the cable as shown in Figure 6 below. Push the shield through the two washers (number 3 in Figure 6 below) and squeeze part of it evenly between them. The shield mesh must not touch the circuit board or its components. Make sure no pieces of the mesh or other metal parts touch the circuit board.
User's Guide ________________________________________________________ Installation Examples Installation with WAC151 and WA25 Wind Set Figure 7 below illustrates a typical installation with WA25 Wind Set. As a power source, it is recommended to use WHP25 Mains Power Supply, with a mast mountable, allweather enclosure. For the wiring instructions, refer to Figure 8 on page 15.
