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 Error! Reference source
not found.. 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.
