B. CONNECTING POWER
Ensure that the AC power circuit breaker is turned off
before wiring power to the switchbox.
Run power cables through conduit to Gate Operator, then
connect wires to the switch box as shown in Figure 11:
1. Wire nut the hot (black) wire to the black pig tail.
2. Wire nut the neutral (white) wire to the white pig tail.
3. Wire nut the ground (green) wire to the green pig tail.
Dress all wiring inside the switch box and install cover.

C. RUNNING INPUT WIRING
1. Remove the plastic control box cover.
2. Run wires from input components and Master/Slave conduits into control box.
3. For Master/Slave wiring, refer to B1 Series Master/Slave Systems
(Doc. No. 6001378).
Route but do not connect input wires at this time. If inputs are connected now, the gate operator
may activate at random during installation, potentially injuring installation personnel.
D. SETTING GATE OPEN DIRECTION SWITCHES (S2, S3)
Figure 12. Gate Direction, Power Fail Option Switch Location.
The gate motion left to right is determined by looking at the gate from the gate operator side.
1. Gate opening direction is set by switch S2, located on the control board. The switch is sensed only
on power up, so it should be set when the power is off.
2. Ensuring power is off, set switch S2 to the right for a Right Gate, or to the left for a Left Gate.
If the system was ordered with the Power Fail Operation option:
3. The power failure gate opening direction is set by switch S3, located next to switch S2 on the
control board.
