Installation
MOUNTING
Mount the unit in a DRY location. Allow at least 4 inches of clearance around it for adequate
cooling.
POWER CONNECTION
The unit is supplied with power leads about 3 feet long. This should normally be adequate to
connect to a source of power. If you must extend the power leads, be sure to use at least a
good quality (typeTEW) wire of at least the same gauge as supplied with the unit. The wire
colours are
All connections should be made inside an appropriate junction box. Refer to the specifications
table for the correct sizing of the circuit breaker in the distribution panel.
A ground stud is provided to bond the chassis to local ground to reduce or eliminate EMI.
OUTPUT CONNECTIONS
Two Positive output terminals and two Negative output terminals are provided. Connect only
one wire to each terminal. Ensure that the total average load connected does not exceed the
continuous current rating of the unit.
LOAD SHARE OPTION
The units may be configured for load sharing if they are equipped with the optional output
isolation diodes. To confirm that your unit has these diodes, use an ohmmeter to
Red - Positive
Black- Negative
measure the resistance between the two positive output terminals. If the diodes are present
the terminals will measure as not connected. If the diodes are NOT present, the terminals
will measure as a short circuit. Assuming the output isolation diodes are present, connect one
4 foot piece of #14 AWG red wire to each positive output terminal. Connect all the positive
wires to a distribution bus, or connect them together, and then connect from the common
point to the load using the correct gauge of wire for the total output capability of all the
