Note: Cable gauges indicate those of HIV cables (maximum heat resistance: 75°C).
*1)Please use the round type crimp terminals ( for the UL standard) suitable for the use electric wire when you
connect the electric wire with the main circuit terminal stand. Please put on pressure to the crimp terminals l with a
crimp tool that the terminal stand maker recommends.
(5) Connecting the control circuit to a power supply separately from the main circuit
If the protective circuit of the inverter operates to open the magnetic contactor in the input power
supply circuit, the inverter control circuit power is lost, and the alarm signal cannot be retained.
To retain the alarm signal, connect control circuit terminals R0 and T0 to a power supply.
In details, connect the control circuit power supply terminals R0 and T0 to the primary side of the
magnetic contactor as shown below.
