please do not connect phase-shift capacitor or lc/rc filter to the output circuit. otherwise'the inverter will
be burned.
ELECTROMAGNETIC SWITCH BETWEEN INVERTER AND MOTOR IS ALLOWED TO USE.
please do not connect electromagnetic switch'electromagnetic contactor to the output circuit.otherwise'
the inverter's surging current will lead to the action of over current protection. in serious case'the inverter's
internal parts could be damaged.
please install a mccb which is compatible to the inverter' capacity .
1 . the capacity of mccb should be 1.5-2 multiples of the inverter's rated current . mccb's time characterics
shall satisfy the inverter's overload protection characteristics (150% of the rated current /minute' 180% of the rated current/2 second )
2 . when mccb is shared by two or above motors or other equipment ' please connect according to the below fig . connect the fault output relay contact of the inverter to the power supply contactor and cut off the
input power supply .
THE INSTALLATION AND SELECTION OF ELECTROMAGNETIC CONTACTOR.
to cut the main circuit power supply at the fault of inveryer and prevent the inverter from restarting at fault' please install electromagnetic contactor on the power supply side of the inverter.
RFI PREVETION SOLUTION.
input cable'output cable and the inverter itself all can create fri. dedicated filter needs to be used at both input
side and output side of the inverter. the normal filter cann't achieve the expected effected. and the input and output terminal shell be custom-made. the rfi can be reduced to use iron device for shielding the connecting
cable between inverter and motor shall be as short as possible. please find below for the rfi prevention.
