DANGER: Risk of electric shock

If the device is disconnected, the secondary side of the relevant current transformers must be short circuited.
Install the current sensors and corresponding measuring devices only when the power supply of the system is disconnected.
When the current transformer is operated with an open secondary circuit, hazardous voltages may occur at the secondary terminal blocks.

 

When measuring by means of current transformers or Rogowski coils, the accuracy is greatly influenced by the quality of the current sensors used. current sensors used. 

Pin assignment example

 

Maximum tightening torque for the relevant screws: 0.5 Nm ... 0.6 Nm.
