When more than 3 amps are required from the MPS-24A/MPS-24AE or when the
secondary power source requirements demand larger batteries than can be adequately
charged by the MPS-24B/MPS-24BE main power supply, an NR45-24/NR45-24E
Remote Battery Charger may be used. The NR45-24/NR45-24E mounts in its own
cabinet, up to 20 feet away from the XP Transponder. The NR45-24/NR45-24E is
capable of charging up to 55 amp-hour batteries, which can be contained in the charger
cabinet.

The NR45-24 requires 120 VAC, 50/60 Hz primary power and the NR45-24E requires
220/240, 50/60 Hz. With the circuit breaker at the main power distribution panel turned
off, connect the AC Hot line to terminal 1 on the NR45-24/NR45-24E and the AC
Neutral line to terminal 2. All connections between the XP Transponder cabinet and
the NR45-24/NR45-24E must be made in conduit, using #12 AWG (3.25 mm
2
) wire.
Do not route AC wiring in the same conduit as other XP Transponder circuits. Leave
the main circuit off until installation of the entire system has been completed.
WARNING: Use extreme caution when working with the APS-6R - high
voltage and AC line-connected circuits are present in the APS-6R. Turn off
and remove all power sources. To reduce the risk of electric shock, make
sure to properly ground the APS-6R. When finished wiring AC connections,
install the press-fit terminal block cover over TB1 AC connections.
