Chapter 3 Notice for wiring
3.1 Precautions for Peripheral Applications
Power supply:
z
Make sure the voltage applied is correct to
avoid damaging the inverter.
z
A molded-case circuit breaker must be
installed between the AC source and the
inverter
Molded-case circuit breaker:
z
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.
z
Do not use the inverter as the switch for
run/stop switch.
Leakage breaker:
z
Install a leakage breaker to prevent error
operation caused by electric leakage and to
protect operators
z
Setting current should be 200mA or above and
the operating time at 0.1 second or longer to
prevent malfunction.
Magnetic contactor:
z
Normal operations do not need a magnetic
contactor. But 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 brake controller.
z
Do not use the magnetic contactor as the
run/stop switch of the inverter.
AC reactor for power improvement:
z
When inverters below 200V/400V 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 (If necessary):
z
To ensure the safety of peripheral devices,
please install the fast action fuse. Regarding
the specification, please refer to P7.
Input noise filter:
z
A filter must be installed when there are
inductive load around the inverter
Inverter:
z
Input power terminals L1, L2, and L3 can be
used in any sequence regardless of phases.
z
Output terminals T1, T2, and T3 are connected
to U, V, and W terminals of the motor. If the
motor is reversed while the inverter is forward,
just swap any two terminals of T1, T2, and T3.
z
To avoid damaging the inverter, do not connect
the input terminals T1, T2, and T3 to AC
power.
z
Connect the ground terminal properly. 200 V
series: class 3 grounding, <100
Ω
; 400 V
series : <10
Ω
