Load balancing refers to ZEFNET software settings that allow the ZEFNET
Pro to share a single circuit entering the unit, instead of the standard two
dedicated circuits the ZEFNET Pro typically requires.
CAUTION:
This is a single-phase device. Do not connect all
three phases of a 3-phase feed!
You may use any two phases
of a three phase wye-transformer feed. The centerpoint of the
three phases (usually used as Neutral) must be grounded
somewhere in the system. A Neutral connection is not required
by the ZEFNET Pro. Only Line 1, Line 2, and Ground are
required, as shown in
Figure 3.
