WARNING! Turn the main power off before
you make any electrical connections or set any
switches inside the control panel enclosure.
For the purposes of installation you need to connect at
least one normally open (N.O.) activating device for
your operator(s).
• If you have a two-leaf gate design,
connect the activating device to terminals
18 and 19.
• If you have a one-leaf gate design, connect
the activating device to terminals 16 and
17.
You use this activating device in the rest of the

require the use of one or more junction boxes. Whether
you need 0, 1, or 2 U.L. Listed junction boxes depends
on your gate design (refer to Figure 15 below).
