CHAPTER 4 - BASIC CONFIGURATION
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 may cause a system malfunction or reduction in product life as well as component
damage. Must be red and understood this manual thoroughly before proceeding.
AC Source Supply
Use the power supply within the allowed
range of inverter input power rating
MCCB or Earth
leakage circuit
breaker (ELB)
Select circuit breakers with care. A high
current peak 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 [*]
The reactors must be used when the
power factor has 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 terminals connection could
damage the equipment .
To the motor
Do not connect any power factor
capacitor, surge suppressor or radio
noise filter to the output side of the
inverter.
[*] Terminal block for DC reactor is available in more than 11kW
capacity.
