The Building Access Controller 32 is powered by a single terminal barrier plug power connector.
To connect the Building Access Controller 32 to a power supply, follow these steps:
1. Always use safe power practices when making power connections. Be sure to remove fuses from
the fuse distribution panel, as well as the back of the Building Access Controller 32, before making
your power connections.
2. Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the symbol
. Insert the eyelet of the earth ground cable between the two bolts on the grounding lug (Ground cable
not included).
3. Insert a battery ground into the power connector plug's right terminal and tighten the screw; then
insert a battery line to the plug's left terminal and tighten its screw.
4. Insert a fuse into the fuse distribution panel and measure voltage. The voltmeter should read
18 and +30VDC.
5. The power plug can be inserted into the power connector only one way to ensure the correct polarity.
Note that the positive voltage terminal is on the left and the GND terminal is on the right.
6. Insert fuse into the Power fuse slot. The power LED should be lit green. If the LED is off, the power
connection may be reversed. To confirm that power is correctly connected, the front panel LEDs will
flash RED and GREEN, indicating that the firmware is booting up.
