Wiring
(1) When using the inverter equipped with a jumper across terminals P1 and
P, remove the jumper and connect the reactor across terminals P1 and
P.

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 )

When using the inverter equipped with a jumper across terminals P1 and
P, remove the jumper. Otherwise, the reactor will not exhibit its
performance.
(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.)
(3) Securely earth (ground) the reactor using the earth (ground) terminal.
CAUTION
1. Do not perform wiring while power is on and the inverter is
running.
2. Any person who is involved in the wiring of this equipment
should be fully competent to do the work.
3. 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 and N is not exceeding 50VDC before
performing wiring.
4. Provide isolation treatment to avoid contact of terminals.
