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 AE-2000 and the power transformer.
• For power wire runs up to 75 feet, use 18 AWG, THHN 600-volt
insulated wire.
• For power wire runs up to 150 feet, use 16 AWG, THHN 600-volt
insulated wire.
2. Connect the wires to the transformer. Connect the other end of the
wires to the AE-2000 AC1 & AC2 terminals.
Backup Battery / Uninterruptable Power Supply
Use of battery backup is optional. It will allow the AE-2000 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.
A backup battery will not fi t into the AE-2000 case. Protect the backup
battery inside a rain-tight NEMA enclosure suitable for the installation.
✦ NOTE: A backup battery is not required to maintain the AE-2000
clock/calendar and programming memory during power outages.
1. Route two wires between the AE-2000 and the backup battery.
2. Connect the Battery positive to the AE-2000 DC+ terminal and the
negative to the DC- terminal.
✦ NOTE: The AE-2000 does not supply battery charging current.
An external battery charger will be required to maintain the battery.
Earth Ground
For the best ground, use size 12 gauge solid wire or larger to connect 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 AE-2000’s EARTH
GROUND STUD.
RS-232 Port
A modular connector is provided for the bi-directional 38.4K baud RS-232
port. The AE-2000’s RS-232 port connects to a personal computer’s COM
port. System programming can be performed locally with a computer
connected to the RS-232 port using the AccessBase 2000 software.
