[. . . ] If not pre-installed by the door manufacturer, mount the sensing edge on the door according to the instructions provided with the edge. The sensing edge may be electrically connected by either coiled cord or take-up reel. Refer to the steps below Important Notes: a) Proceed with Limit Switch Adjustments before making any sensing edge wiring connections to operator as described below. b) Electrician must hardwire the junction box to the operator electrical box in accordance with local codes. IT IS STRONGLY RECOMMENDED THAT A SENSING EDGE OR OTHER ENTRAPMENT PROTECTION DEVICE BE USED IN CONJUNCTION WITH THIS OPERATOR.
TAKE-UP REEL: Take-up reel should be installed 12" above the top of the door. COIL CORD: Connect operator end of coil cord to junction box (not supplied) fastened to the wall approximately halfway up the door opening.
MGJ LIMIT SWITCH ADJUSTMENT
MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE PROCEEDING WITH ADJUSTMENTS. To adjust limit nuts depress retaining plate to allow nut to spin freely. After adjustment, release plate and ensure it seats fully in slots of both nuts. Adjust open limit nut so that door will stop in open position with the bottom of the door even with top of door opening. Adjust close limit nut so that actuator is engaged as door fully seats at the floor.
WARNING
TO AVOID SERIOUS PERSONAL INJURY OR DEATH FROM ELECTROCUTION, DISCONNECT ELECTRIC POWER BEFORE MANUALLY MOVING LIMIT NUTS.

Auxiliary limit switches to control other functions are also present and should not be confused with the -Aand -B- limit switches. There are two(2) limit nuts on the threaded shaft that transverse the shaft as the operator opens and closes the door. When a limit nut nears the end of the shaft, it activates a switch(es).
WARNING
A. Set Limit Direction Switch Open the cover on the electrical enclosure and locate dip switch SW1 on circuit board. The direction of the limit travel is determined by the switch SW1 - pole #2 setting.
B. Depress the limit nut retaining bracket away from the slots in the limit nuts, and manually rotate to the OPEN limit nut until it depresses the OPEN limit switch lever (you can hear the switch click when the switch contacts transfer). Lubricate. * Check set screw tightness Check & tighten as required Check & Operate Check for wear & lubricate
