AC 3PHASE INVERTER,S CONTROL CIRCUIT TERMINAL WIRING DESCRIPTION





















CONTROL CIRCUIT TERMINAL WIRING DESCRIPTION.

to reduce the control signal's interference and attenuation' the control signal's wiring length shell be limited within 50 cm and the distance to the power cord shell be longer than 30 cm. when connecting the along input and output signal' please use twisted pair cable and connect one end of the shielding sleeve to the ground.

CONTROL CIRCUIT CONNECTION NOTES.

to layout separatedly the control circuit cable'main circuit cable and other power supply cable. to avoid from
the wrong operation cased by interference' control circuit cable needs to be twisted pair cable. the connection distance shall be less than 50 m. the distance to power cable needs to be more than 30 cm. please use twisted pair cable for the command from terminal. please see below when the output contact of multifunction  optical coupler connects to relay' coil's two ends needs to connect to bypass diode in parallel.
please do not make shielding cable connect to the single cable or machine's housing. the naked wire shall be
wraped by isolation tape.
contact output terminal 9'10'18'19'20' must be connected to terminal 1~8'11~17'21~23'25~27'33 independently.
