CAUTION
To prevent a malfunction due to noise, keep the signal cables more than 10cm (3.94inches)
away from the power cables.

REMARKS
To ensure safety, connect the power input to the inverter via a magnetic contactor and earth
leakage circuit breaker or no-fuse breaker, and use the magnetic contactor to switch power on-off.
The output is three-phase 200V.

CAUTION
The power supply cables must be connected to R, S, T. If they are connected to U, V, W,
the inverter will be damaged. (Phase sequence need not be matched.)
For use with a single-phase power supply, the power supply cables must be connected to
R and S.
Connect the motor to U, V, W.
Turning on the forward rotation switch (signal) at this time rotates the motor
counterclockwise when viewed from the load shaft.
