*    Cable distances are based on:

26.4 VAC output from the controller (24 VAC models), or
132 VAC output from the controller (120 VAC models), or
12 VDC output from the controller (12 VDC models), and
10% cable loss with both motors (pan and tilt) running simultaneously

**   Six conductors for operating pan and tilt motors:
