1. Safety Tips

The installation, connecting or debugging of the production should be done following the instruction of the manual; at the same time, pay attention to the wiring diagram and the sign of Terminal point at the rare of the controller.  

When the shell of controller was broken or the monitor not working , stop using it and connect with supplier. 

The installation should strictly follow the operating instruction in the respect of the standard of safety. Follow the correct way of wire connecting and electric wire size to guarantee the safety, reliability of operation, and the accuracy of measure.    

When connecting with electricity, both side of CT will generate High-voltage surge which is dangerous to our life. Be careful when operating, strictly follow the operating instruction of safety utilization of electric power.

Only trained work allowed to use according the instruction and safety regulation.
