Main power terminals

Do not connect 3-phase model to one-phase power. R/L1, S/L2 and T/L3

has no phase-sequence requirement, it can be used upon random

It is recommend to add a magnetic contactor (MC) to the power input wiring

to cut off power quickly and reduce malfunction when activating the

protection function of the AC motor drive. Both ends of the MC should have

an R-C surge absorber.

Fasten the screws in the main circuit terminal to prevent sparks condition

made by the loose screws due to vibration.

Please use voltage and current within the specification.

When using a general GFCI (Ground Fault Circuit Interrupter), select a

current sensor with sensitivity of 200mA or above and not less than

0.1-second operation time to avoid nuisance tripping.
