To check if that your unit has these diodes
Use an ohmmeter to 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.
1. Assuming the output isolation diodes are present, connect a one-foot piece of red wire of
the appropriate gauge (as shown in the table above) to each positive output terminal.
2. Connect all the positive wires to a distribution bus, or connect them together.
3. 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 the above steps for the negative terminals using the same gauges of black wire.
These units should now load share, you can use an ohmmeter at the load to confirm this. A
slight difference is acceptable. If there is more than a slight difference, then adjust the output
voltage as shown under
Operation.

Load Sharing (Option D)
The Load Sharing Option (Option D) allows the unit to be connected in parallel with other
voltage converter to power a single load. To accommodate this function, special output
isolation diodes are present in the unit to prevent current from back feeding into the unit. In
addition, the peak current is lowered to the continuous rating for safety purposes.
