The overload relay trip setting must be adjusted to
Correspond with the motor full load current as shown on
the motor nameplate.
Control transformer shown for 460V primary. For 200 or
230V or 575V refer to Inset A.
Relay(s)--contacts: silver-cadmium oxide: 1/6 hp 5 amp @ 120V
AC, 1/3 hp 5 amp @240V AC. See 24V schematic diagram for
coil connections and actual quantity of transformer relays.
Closes to run auto mode or bypass auto for option VFD or
starter.
Program terminal 27 inv. coasting stop.
Program terminal 18 as run.
The minimum circuit ampacity, the maximum fuse size, and
disconnect size are calculated based on the inverter input
line currents per article 430-2 of the National Electrical
Code.
All field wiring must be in accordance with the National
Electrical Code (NEC), state and local requirements. Other
countries applicable national and/or local requirements
shall apply. Field conductors shall have insulation
rating not less than 600v copper conductors only.
Dashed lines indicate recommended field wiring by others.
Phantom lines indicate control option.
Ref. Control panel schematic for specific detail.
