Output Load Connection Configurations
The same output terminal is used to support all output phase modes and DC output mode.
The output terminal post are marked from left to right as “A” “B”, “C”, “N” and Ground
(Symbol).
The correct wiring for each mode is shown in the table below and is also printed on the rear
panel on the power source, directly below the output terminal block.

Recommended Output Wire Size
A major consideration in making load connections is the wire size. The minimum wire size is
required to prevent overheating and to maintain good regulation. It is recommended that
the wires are sized large enough to limit the voltage drop at the maximum current rating of
the power source to no more than 0.25V per lead when sensing internally (at the output
terminal, not the load).
Recommended copper wire gauges are shown in the tables below by model and output
mode for the highest current, which occurs on the low voltage range. Aluminum wire is not
recommended. Keep the distance between the power source and load as short as possible
for best results.
