3.1 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 Source
Supply
Use the power supply within the
permissible range of inverter input power
rating (Refer to Page 197).
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 and DC
Reactors
notice1
The AC reactors must be used when the
power factor is to be improved or the
inverter is installed near a large power
supply system (more than 10 times of
inverter capacity 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.
