3.3.3 Precautions for peripheral applications:
Power supply:
Make sure the correct voltage is applied to avoid
damaging the inverter.
A molded-case circuit breaker or fused disconnect
must be installed between the AC source and the
inverter
Molded-case circuit breaker:
Use a molded-case circuit breaker that conforms to
the rated voltage and current of the inverter to
control the power ON/OFF and protect the inverter.
Do not use the circuit breaker as the run/stop switch
for the inverter.
Leakage breaker:
Install a leakage breaker to prevent problems caused
by electric leakage and to protect personnel.
Setting current should be 200mA or above and the
operating time at 0.1 second or longer to prevent
malfunctions.
Magnetic contactor:
Normal operations do not need a magnetic contactor.
However a contactor has to be installed in primary
side when performing functions such as external
control and auto restart after power failure, or when
using a brake controller.
Do not use the magnetic contactor as the run/stop
switch of the inverter.
AC reactor for power quality improvement:
When inverters below 400V class 15KW are
supplied with high capacity (above 600KVA) power
source or an AC reactor can be connected to
improve the power performance.
Install fast action fuse:
To ensure the safety of peripheral devices, please
install fast action fuse. Regarding the specification,
please refer to P3-4.
Input noise filter:
A filter must be installed when there are inductive
loads affecting the inverter
Inverter:
Input power terminals L1L2L3can be used in
any sequence regardless of phase.
Output terminals U, V, and W are connected to U,
V, and W terminals of the motor. If the motor is
reversed while the inverter is set to run forward, just
swap any two terminals of U, V, and W.
To avoid damaging the inverter, do not connect the
input terminals U, V, and W to AC input power.
Connect the ground terminal properly. 400 V class:
grounding, <10
