DC reactor terminal. Please remove the jumper before installation
Braking resistor terminal. Select option as per the specifications. (Please
refer to Chapter 7.1)
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
