If AC power is connected, the system does not need the batteries to function. However, the batteries must be connected for
the Power Fail Battery Backup features to operate. When AC power is active, the batteries will charge until fully charged.
Once the batteries have fully charged, the system will stop charging. Charging is automatic when AC power is available. The
system should be prewired with the batteries. If not, to connect batteries to the system:
1. Connect the RED wire from the B Terminal to the positive terminal of the first battery.
2. Connect the BLACK wire from the Battery - Terminal to the negative terminal of the second battery.
3. Connect a jumper between the remaining terminals of each battery.

Two plug-in power plugs are located on the back of the controller. These plugs are for low voltage accessories and are
separately fused. Low voltage, low current draw transformers may be plugged into these outlets for accessory power. DO
NOT USE THESE POWER OUTLETS FOR INSTALLATION OR SERVICE TOOLS. Each plug supplies 110 VAC when AC
power is active to the gate operator. If AC is not available, the power plugs will not supply power. Accessories requiring power
during battery backup modes should use the 24 VDC located on the controller terminals.
Additional accessory power may be found on the controller terminals. The controller terminals supply 24 VDC for accessories.
This power is available during AC and battery power modes. When AC power is active, accessories will be supplied 24 VDC
without a power draw on the batteries. When the battery backup mode is active, accessories will be supplied 24 VDC from the
batteries. If the battery power mode is used frequently, consider the current draw of the accessories. The lower the current
draw, the longer the battery power supply will last. Additional 24 VDC for accessories may be found on the Radio Terminal,
Edge/Photo Terminal, and External Loop Terminal. A connection between 24V DC+ and Common will supply power.
Batteries should be tested regularly for proper battery backup operation.
Batteries should be replaced each year or as needed.
