ACCESSORY AND RELAY CONNECTIONS

These terminals will provide battery backed power to 24 Vdc devices and are located
at the bottom of the control board at J4 terminals 1 and 2. Terminal 1 is 24 Vdc (+)
and number 2 is 0 Vdc (-). Peripheral CLASS 2 low voltage devices that require
24 Vdc power maybe connected here (500 ma. maximum).

EXAMPLE:

Vehicle detector, radio receiver.

Connect AC power BEFORE installing batteries.

Install two new, fully charged 12 volt DC batteries on shelf next to motor.

Connect red lead from the operator control board to the positive (RED +)
terminal of one battery.

Connect the black lead from the operator control board to the (BLACK -)
terminal of the OTHER battery.

Connect the jumper (provided) between the remaining terminals of each
battery if one is not already in place.

IMPORTANT:

Do not run operator without installing the batteries.

Replace batteries in pairs using LiftMaster MBAT or 29-NP712 batteries. Failure to
install batteries correctly will cause damage and will not be covered by warranty.
