Internal Alarm Card
The alarm card provides voltage free relay contacts in the event of:
• AC failure
• SPS failure
• SPS Shutdown Mode (over temperature, over voltage, current limit)
• High voltage output
• Low voltage output
When SPSs are connected in parallel using an RJ45 patch cable (Newmar part # 466-4524-0) to connect between
the alarm and control interface on each rectifier, the alarm outputs on the Alarm Card give the status of all the
connected units. This means that only one alarm card needs to be connected to the alarm circuitry when the
rectifiers are connected in parallel.

Installation
2.1
General Warnings
The SPS contains no user serviceable components. Do not disassemble the SPS.
To isolate the SPS from AC power, simply unplug the IEC mains connector from the rectifier.
DANGER
Do not operate the rectifier if the covers are damaged or removed in any way.
• The rectifier contains voltages that may be lethal even after the input supply has been
removed
• The rectifier contains components at High Temperatures that may burn if touched

Positioning of SPS
A great deal of care should be taken with positioning the unit, as the position can affect its life expectancy and
performance.
This unit MUST be mounted on a wall or vertical surface using the side mounts. Observe the up ^ arrow printed on
the lower left of the front panel.
The SPS should be positioned close to the load and batteries, so as to keep the length of the low voltage cables to a
minimum. These cables are carrying high currents, and voltage drop in the cables must be kept to a minimum. It
is better to have a long AC lead and short DC voltage cables.
The rectifier must be positioned so that airflow through the rectifier is not impeded in any way. These rectifiers are
convection cooled – their performance and life expectancy is reduced if the airflow is impeded.
The SPS should not be mounted above another rectifier or a source of heat.
The rectifier should be mounted 2 inches clear of any other solid object, and care should be taken to ensure that
air entering the rectifier is cool air, and has not been heated by other equipment.
