Wiring

(1) Remove the jumper across terminals P-P1 of the inverter and connect
the reactor.
• Minimize the connection cable between the reactor and inverter so that the
length is within 5m. (For the size of the cable, refer to page 4)
• The jumper connected across terminals P1-P must be removed. Otherwise,
the reactor will not exhibit its performance.
Reinstall the terminal block cover after wiring.

(2) Make selection according to the applied motor capacity. (When the
inverter capacity is larger than the motor capacity, make selection
according to the motor capacity)
For a motor of less than 0.4kW, choose the option designed for 0.4kW.
CAUTION
1. Remove the terminal cover of the terminal block to perform
wiring. Reinstall the wiring cover after performing wiring.
2. Do not perform wiring while power is on and the inverter is
running.
3. Any person who is involved in the wiring of this equipment
should be fully competent to do the work.
4. Since high-voltage is applied to the inverter terminals P1, P and
N, fully make sure that the input power is off and the voltage
across terminals P-N is not exceeding 50VDC before
performing wiring.
5. The terminal block cover is not provided for the 200V class
18.5K or more.
Provide isolation to avoid contact of terminals.
Remove the jumper
across terminals P-P1.
