PE must be protective earth = safety ground. It should be connected to
the 120 V neutral ONLY at the circuit breaker box, not in the equipment,
unless you won't be running a separate wire to the unit. That would be
a violation of the national electrical code.

If this is truly a 220 V motor, and there are no other 120 V loads in
the equipment, then there should be no neutral wire. Just 2 lines
and a safety ground.
