2. Terminals P1, (+), PB and (-) connects the DC reactor options and parts.
C.4 Breaker and electromagnetic contactor
It is necessary to add fuse for the avoidance of overload.
It is appropriate to use a breaker (MCCB) which complies with the inverter power in the 3-phase AC power
and input power and terminals. The capacity of the inverter should be 1.5-2 times of the rated current.
 Due to the inherent operating principle and construction of circuit breakers,
independent of the manufacturer, hot ionized gases may escape from the
breaker enclosure in case of a short-circuit. To ensure safe use, special attention
must be paid to the installation and placement of the breakers. Follow the
manufacturer's instructions.
It is necessary to install the electromagnetic contactor in the input side to control the switching on and off
safety of the main circuit. It can switch off the input power supply when syatem fault.
