Step 18: Mount Wired Infrared Safety Sensors 
Attach the sending and 
receiving units to the “U” 
brackets by inserting their tabs 
into their respective holes.
Step 19: Connecting Electrical Power 
To reduce the risk of electrical shock, 
connect the power cord only to a 
properly grounded 3 prong, 120 volt 
outlet. 
Do not use an extension cord or change 
the plug in any way. At this point, plug in 
the opener to an electrical outlet. If the 
plug does not fit into the outlet, or you 
require permanent wiring, contact a 
qualified electrician to install the proper 
outlet. As soon as power is applied to 
the unit, the light on the opener will blink 
once to indicate a successful self-check of the controls. 
WARNING: Check your local electrical 
codes. If your local code requires perma-
nent wiring, use the specifications called 
for and instructions illustrated.
