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) AWG12 wire. The wire colours are

All connections should be made inside an appropriate junction box. Refer to the specications

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 congured for load sharing if they are equipped with the optional output

isolation diodes. To conrm that your unit has these diodes, use an ohmmeter to measure the

Red - Positive Black- Negative

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 distribu-

tion 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 supplies running in paral-

lel. Repeat this process for the negative terminals using the same gauges of wire, but black

in colour. These units should now load share. You can conrm this by watching the output

ammeters. A slight difference is negligible, however, if this is not the case, you can increase

the output voltage of the unit that is reading low using the output adjust potentiometer.
