Precautions
  Recommended connection cable diameter is 1.5 square, Maximum is 2.5 square
  Communication cable can be the shielded cable. And the cables of input, communication and power should be routed separately. Pay attention to environmental conditions, whether there is some corrosive gases or not. If any, you should notify the manufacturer when ordering
 When adjusting the live programming current transformation ratio, it should correspond to the specifications of primary current transformer
 Be sure of cutting off the power supply product installing, when disassembling maintenance checking and wiring, otherwise it will cause to shock or burnt the equipment
 Switch input power is DC voltage, you must follow the correct polarity connection
