AC POWER CONNECTION
To connect AC power to the controller:
1. Turn the circuit breaker for the AC gate operator power OFF
before connecting the AC input wires.
2. Turn OFF the Power Switch located on the left side of enclosure
before connecting the AC input wires.
3. Connect the AC input wires to the AC terminal located on
the top left of the control box. See diagram below.
4. Batteries must be installed after the AC power is on. See
Battery Power Connection.
AC POWER GUIDELINES:
THE E024U control board and power supply uses a single phase
AC power line to operate, charge the batteries, and power
gate accessories. Use the following guidelines when installing
the AC power:
1. Check the local wiring codes in all cases and follow all local
building codes. Wiring and hookup should be performed by a
qualified electrician/installer only.
2. AC power should be supplied from a circuit breaker panel
and must have its own dedicated circuit breaker. This supply
must include a green ground conductor.
3. Use copper conductor wires with liquid tight flexible conduit

4. Properly ground the gate operator to minimize or prevent
damage from power surges and/or lightning. Use a grounding
rod if necessary. A surge suppressor is recommended for ad-
ditional protection.
