Wiring Connections 
 
The rotator unit must be wired to the 
control unit with 4-wire cable. The 
gauge of the 4-wire cable to connect the 
control unit to the rotator depends upon 
the distance between rotator and 
controller. The wire for the impulse 
sensing may be quite thin - #22 or similar, even for relatively long 
distances.

TIP:
Before final installation of
