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 shipped
from the factory with a short-circuit jumper. Remove the jumper before connecting a DC
reactor.

DC Reactor (option)

If the drive is used in a high-frequency or heavy duty application which requires frequent
braking or shorter deceleration time, install an optional braking resistor to increase the
braking torque.

Braking Resistor (option)

Please refer to the wiring diagram when installing braking options.
