Main circuit terminal block
The terminal block for connecting the main power supply for the inverter, outputs to
the motor, Braking Resistor, etc.
Lights up even after power supply shutoff if the main circuit DC voltage (between the
terminal P/+2 and terminal N/−) is approximately 45 V or higher. Make sure the
charge indicator is not lit before wiring etc.
Note For the description of the data display and operation keys, refer to Section 3 Operation and Test Run.
