4.5 Wiring of Main Circuit
4.5.1 Power Supply Connection of Main Circuit
4.5.1.1 Breaker
Between 3ph AC power supply and power input terminals (R, S, T), it is necessary to
connect a breaker which is compatible with the capacity of inverter. The capacity of breaker is
1.5-2 times to the rated current (amperage) of inverter. For details, please refer to
Specification Table of Breaker, Cable, and Contactor
4.5.1.2 Magnetic Contactor
In case of system malfunction and that the power input of inverter must be cut off
completely for safety, magnetic contactor can be installed at the power input side to control the
on/off of the main circuit power supply.
4.5.1.3 Input AC Reactor
In case of high voltage input from power grid and so heavy current flowing into power
supply circuit damages components of rectifier
it is necessary to install and connect a AC
