Using the ALC Power Supply
The PWRSUP8500 power supply replaces both
the Johnson Controls LPS-105 and Johnson
RPA-105. The PWRSUP8500 is designed to fit
into the previous power supply's mounting
bracket and power the InterOP8500. The
PWRSUP8500 does not require any adaptor
cables. It connects directly to the
InterOp8500's power connector.

CAUTION The PWRSUP8500 module is a
120VAC device. Take appropriate isolation
measures when mounting a PWRSUP8500.
1. Turn the power switches off on the
InterOP8500 and the Johnson Controls
panel.
2. Unplug the LPS-105 from the power outlet
(see Figure 5).
3. Remove the power cable from the
InterOP8500 power connector.
4. Take out the mounting screw from the
face of the LPS-105 and remove the LPS-
105 from the Johnson Controls panel.
5. Take out the mounting screw from the
back of the RPA-105 and remove the RPA-
105 from the Johnson Controls panel.
6. Place the PWRSUP8500 in the same
brackets that the RPA-105 was in. Make
sure the edges of the PWRSUP8500 are in
the slots.
7. Replace the mounting screw in the back
of the PWRSUP8500 (see Figure 3 on page
5).
8. Connect the power cable of the
PWRSUP8500 to the InterOP8500 power
connector and plug the PWRSUP8500 into
the power outlet.
9. After verifying that you have +5V on the
red and +12V on the blue, referenced to
the Gnd (black), turn the InterOp8500
power switch on.
