4.2.2 Main Circuit Wiring
4.2.2.1 Power Input Terminal

Install a molded case circuit breaker (MCCB) between three phase AC input power and
main circuit terminals R/L1, S/L2 and T/L3. A magnetic contactor (MC) in series
connection is also suggested so as to shut off the power by drive protection functions.
Install a R-C varistor on both ends of the MC.

Ensure main circuit terminal screws are tightened to avoid vibration loosening the screws
which could cause electric sparks.
4.2.2.2 Power Output Terminal

When connecting a noise filter at AC drive output terminals U/T1, V/T2 and W/T3, always
use an inductive L-filter. Do not install any power capacitor, L-C or R-C filter.

Connect AC drive output terminals U/T1, V/T2 and W/T3 to motor input terminals U, V
and W respectively. Ensure the motor and drive terminals are in same phase sequence or
the motor will rotate reversely.

Do not connect power cable to output terminals of the drive. Failure to comply could
cause drive damage and a fire.
4.2.2.3 DC Reactor and Braking Resistor Terminal:

The terminal is to connect a DC reactor so as to improve power factor. The drive is
