Installing the battery backup, AC fail, and low battery
The battery backup acts as a temporary power supply to the M3000 when AC power is lost. The battery
included with the enclosure is 12 VDC with a 12 AH current rating. It will need to be wired to the power
supply. Refer to
Chapter 10, Troubleshooting, maintenance & support on page 151 for battery removal and
installation procedures.
To install the battery
1. Unpack the battery from the shipping box.
2. Place the battery inside the enclosure below the power supply as shown in Figure 6 on page 20.
3. Remove the protective cover from the positive terminal of the battery.
4. Connect the battery leads from the power supply: Black to negative terminal and Red to positive
terminal of the battery. Figure 8 shows the wiring between the battery and the power supply.
Wiring AC power fail
The power supply includes a relay that monitors and signals the loss of AC power. The power fail line is low
during normal operation, and goes high when AC input power is lost.
If this option is used, connect the power supply AC power fail NC and COM terminals to the Power/
Communications Board connector J6, pin 6 (ground) and pin 8 (AC power fail input). See
Figure 8 on page 23.
Wiring low battery detect
The power supply includes a low battery relay to detect and signal a low battery condition (11 VDC or less).
If this option is used, connect the power supply low battery NC and NO terminals to the 20DI Board connector
J2, pins 1 and 2. Install 2K resistors at power supply terminals. See
Figure 8 on page 23.
CAUTION: Make sure AC input and battery backup power is disconnected prior to installing CPU, reader, DI, and
DO boards.
CAUTION: Replace battery with lead acid sealed 12 AH only.
