2.6.3 Alarm Wiring in Parallel
The internal alarm cards of multiple parallel units can be connected in parallel (using RJ45 Cat. 5 style patch
cord, Newmar part # 466-2524-0, 24” length) so that the alarm condition can be reported if any alarm is triggered
in any SPS.
When units are connected in parallel (and load sharing), the alarm outputs give the status of all the SPSs in
parallel. This means that you only need to connect one alarm card to the alarm circuitry when the units are
connected in parallel.

Start-UP
1) Make sure that all cables and wires are disconnected from the SPS.
2) Plug the AC cable into the SPS and switch the AC on at the outlet. The AC LED should glow green.
3) Disconnect the mains, then plug in the Temperature Compensation Probe, re-connect AC and check that
the Temperature Probe LED is green.
4) Disconnect the AC, then double check the polarity of the cables from the battery (there should be a fuse in the
battery lead as close as possible to the battery to protect the wiring from faulty connections) and
then plug them into the SPS. Re-connect the mains and the Float Boost LED should glow first yellow then
after about 10 seconds either green or yellow depending on the charge of the battery. The display LEDs should
give an indication of the current from the rectifier.
5) Disconnect the AC, then double check the polarity of the cables to the load, and then plug them into the
SPS. Re-connect the AC.
6) If there is more than a unit connected in parallel, then follow the above procedure for each in
turn (with the others all disconnected). Ensure all SPSs are adjusted to the same output voltage
(better than ±0.1V) Finally connect the Load Share Signal cable between the units, and check that all
are indicating near equal current (should be better than 10% of full load).
7) Connect the alarms (if fitted/used) and check their operation.

Servicing
If the rectifier develops an operational fault or is damaged in any way, contact NEWMAR technical assistance by

Warnings
This rectifier contains no user serviceable components. Do not disassemble the rectifier.
To isolate the unit from the AC, simply unplug the IEC connector from the unit.
