2. INSTALLATION
Figure WA35095 illustrates mounting of the WAC151 to the top of a Ø 60
mm pole mast, with the standard mounting clamp. For installation, follow the
procedure below:
1
Remove the four screws attaching the cover of the WAC151 unit.
Remove the cover.
2
Enter the power and signal cables through the cable glands(s). For better
protection against RF interference, follow the earthing instructions of
the cable shield in drawing WA35095.
3 Do the wiring to the screw terminal block according to the drawing
WA35172. Notice that the factory wiring is for WAA151 & WAV151
sensors. If WAA251 is used with WAV151, 10 k Ω NTC (delivered with
the WAA251) must be used instead of thermostat. Tighten the output
cable gland(s).
4
Carefully reattach the enclosure cover with the four screws.
5
Attach the unit to the top of a pole mast with the mounting clamp.
