■ Wiring
◎Ensure only qualified electrical engineering personnel for wiring work . Otherwise it
can cause an electrical shock or damage to the VFD.
◎Make sure VFD is isolated from power supply by the circuit breaker. Otherwise it may
cause electrical shock or a fire.
◎Make sure that the ground terminal is grounded correctly. Otherwise it may cause
an electrical shock.
◎Do not touch the main circuit terminals, and keep the wiring of VFD main terminals
from contacting to the enclosure, or it can cause electrical shock.
◎Terminals for brake resistor are (+) and PB. Do not wire to other terminals, otherwise
will cause a fire.
◎Before wiring, ensure the VFD’s rated input voltage and phases is compatible to the
input power source, or it can cause a fire or personal injury.
◎Never connect the AC power supply to output terminals U, V and W. Otherwise the
VFD will be damaged and the guarantee is voided.
◎Never carry out withstand voltage test to the VFD, for example by a megohm meter.
Otherwise it may cause damage to the VFD.
◎VFD’s main circuit wiring and control circuit wiring should be separated, or run
vertically from each other. Otherwise it may cause interference to the control signals.
◎Main circuit wiring cable leads should be crimped with cable lugs in insulated sleeve.
◎If the cable length between the VFD and the motor is greater than 50 meters, it is
recommended to use an output reactor to protect the VFD and the motor.
