4.1 Connection of peripheral devices to the inverter
The following devices are required to operate the inverter. Proper peripheral devices must be selected and correct
connections made to ensure proper operation. An incorrectly applied or installed inverter can result in system malfunction
or reduction in product life as well as component damage. You must read and understand this manual thoroughly before
proceeding.
AC Supply Source
Use the power supply within the permissible
range of inverter input power rating. (See
14.Specifications)
MCCB or Earth leakage
circuit breaker (ELB)
Select circuit breakers with care. A large inrush
current may flow in the inverter at power on.
Magnetic Contactor
Install it if necessary. When installed, do not use it
for the purpose of starting or stopping. Otherwise,
it could lead to reduction in product life.
AC/DC Reactors
The reactors must be used when the power factor
is to be improved or the inverter is installed near a
large power supply system (1000kVA or more and
wiring distance within 10m)
Installation and wiring
To operate the inverter with high performance for
a long time, install the inverter in a proper place in
the correct direction and with proper clearances.
Incorrect terminal wiring could result in the
equipment damage.
To motor
Do not connect a power factor capacitor, surge
suppressor or radio noise filter to the output side
of the inverter.
