4.1Connection 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.

 

Use the power supply within the

AC Supply Source

permissible range of inverter input power

rating. (See Error! Reference source

not use it for the purpose of starting or

stopping. Otherwise, it could lead to

 

 

reduction in product life.

 

 

 

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)

 

 

 

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.

 

 

 

Do not connect a power factor capacitor,
