Power, Battery, & Ground Wiring

Power Wiring

✦NOTE: DO NOT APPLY POWER UNTIL THE INSTALLATION IS COMPLETE.TURN MASTER POWER SWITCH OFF BEFORE WIRING.

1.Route two wires between the AM3Plus and the power transformer.

• For power wire runs up to 100 feet, use 18 AWG, 600-volt insulated wire.

• For power wire runs up to 200 feet, use 16 AWG, 600-volt insulated wire.

2.Connect the wires to the transformer. Connect the other end of the wires to the AM3Plus AC1 & AC2 terminals.

Backup Battery

Use of battery backup is optional. It will allow the AM3Plus to operate for short periods of time without AC power. The door or gate access device must use some type of battery backup of its own for the entire system to be functional.

Use a 12-volt gel-cell type battery. Up to a 7-amp/hr. battery will ﬁ t into the AM3Plus cabinet. Do not use a 6-volt battery.

✦NOTE: A backup battery is not required to maintain the AM3Plus clock/calendar and programming memory during power outages.

1.Route two battery leads between the AM3Plus and the backup battery.

2.Connect the Battery positive to the AM3Plus BAT+ terminal and the negative to the BAT- terminal.

✦NOTE: The AM3Plus supplies battery charging current. An external battery charger is not required to maintain the battery.

Earth Ground

For the best ground, use size 12 gauge solid wire or larger to connect the to an 8-foot copper ground rod. Locate the ground rod next to the Power and Telephone company rods and bond the rods together with a new clamp. Do not disturb the clamps installed by the Power or Telephone Company. Alternately, connect to a metallic cold water pipe for the earth ground.

1.Connect the wire from the earth ground to the AM3Plus EARTH GROUND terminal.
