    Wiring diagram

    (1) The instrument wiring adopts Pluggable connecting terminal ;
    (2) The soft copper cross-sectional area of the input side wire must be greater than 0.5mm2, and the output side must be greater than 1mm2;
    (3) The exposed length of the wire is about 8mm, which is locked by M3 screws;
    (4) The output contacts must provide enough fuse protection connections;
    (5) Copper conductor must withstand an ambient temperature of at least 75 ℃; 
    (6) Terminal screws can cause misoperation, heating, etc. Therefore, please tighten it according to the specified torque. Terminal screw tightening torque 0.5Nm.
