ASSOCIATED EQUIPMENT PERFORMANCE
• Connect 3-phase AC input power wire to
terminals L1, L2, and L3. See the connection
drawing inside the cover of the unit.
• Depending on the configuration of the
equipment, input power may be connected to
a circuit breaker or input disconnect.
• Torque terminals in accordance with the
information provided on the connection
diagram inside the cover of the unit.
• Use with Isolated Input Source. Many
utility power systems are referenced to earth
ground. Although not as common, the input
power may be an isolated source. All drives
may be used with an isolated input source
as well as with ground reference power
lines.
