Installation Instructions
Use a licensed electrician for the following steps.
1.
Make sure the power switch is in the OFF position. If it is not, move the toggle switch to the OFF
position (Figure 25).
2.
Using a screwdriver, remove the cover of the junction box.
3.
Locate the power wires inside the junction box.
4.
Run the primary power wires, coming in from either side of the top channel, through the knock-out.
NOTE
The junction box housing has circular knock-outs on the side of the box. Remove the most appropriate knock-out.
Both junction boxes will need to be wired for power. The easiest way to accomplish this is to wire the two junctions
boxes together. The junction boxes must be wired in series. It is strongly recommended that a licensed electrician
perform this step.
5.
Secure primary power wires to the provided pig-tail in the junction box and secure with wire nuts. See Figures
26 for 110V & 220V configurations.
6.
Tuck the excess wire into the junction box and re-attach the junction box cover.
7 . Once power has been established, route the access control wires.
NOTE
If your model was purchased with the option of having a card reader installed, please refer to the installation
instructions that come packaged with the card reader mounting plate.
