5.4 New Battery Back-Up Installation
If the original system did not have a battery back-up but one is desired later, order Kit #064-511889-K and
follow the steps below.
1.
Turn off the main AC power to the RAC5 XT or disconnect the power adapter.
2.
Connect and secure the fork-crimp terminal end of the red wire to the (+) terminal on the power supply
terminal block BAT.
3.
Connect and secure the fork-crimp terminal end of the black wire to the (-) terminal on the power supply
terminal block BAT.
4.
Place the battery back-up in the enclosure as shown in Figure 10.
5.
In order: Install the battery brackets, flat washer, split washer and nuts.
6.
Connect the wires from the power supply to the battery ensuring that the red wire connects to the (+)
terminal and the black wire connects to the (-) terminal.
7.
Reconnect the power adapter and/or main AC power to the RAC5 XT.
NOTE:
For preventive maintenance, the battery back-up should be replaced every 2 to 3 years and tested
every 6 months by removing the main AC power.
5.5 Power Failure
In the event of an electrical failure, the system will recover automatically and should require no additional
programming if electrical power is restored within 3 days.
When electrical power is restored after a power failure, verify the status of the LED D46 on the controller board
(B) is blinking. Refer to Annex A for Status LED definitions.
NOTE:
When the power to the RAC5 XT is lost, the controller PCB stops functioning and the on-board relay will
return to its normal state. Any peripheral connected to the relay will then be either in a Normally Open (NO) or
Normally Closed (NC) state, dependent on the wiring.
5.6 Loading Recommendations
Do not exceed the load limitations of the control panel.
The maximum recommended load for the output relays in the RAC5 XT system is 1 Amp at 30 VDC. The tamper
switch rating is 1 Amp at 30 VDC.
The current supplied by the controller PCB is for the locking device used is 0.54 Amps from connector J18 pin 1
and J6 pin 1. Refer to Annex A.
5.7 System Deactivation
In order to deactivate the RAC5 XT system, disconnect both terminals from the battery back-up (if equipped),
then disconnect the AC power either by removing the power adapter from the wall outlet, or by shutting off the
main power to the electrical outlet the system is connected to.
