Specifications
Phase.Converter
The power from the manufactured power leg (wild wire)
of a phase converter fluctuates, which may damage elec-
trical components if connected to the wrong incoming
power terminal. If you must use a phase converter for
3-phase power, only connect the "wild wire" to the L1
terminal. The wire from the L1 terminal can handle some
fluctuation because it goes directly to the motor. The
power going to the L2 and L3 terminals connects to the
controls and must be consistent to prevent damage.
