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
Red - Positive Black- Negative
Installation
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 supplies
running in parallel. 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 confirm 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 potentiom-
eter.
