Connecting Supply
What you will find in this section:
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.
Schematic for connection types
Power supply option - Low-voltage grids:
You can connect the device supply as follows:
- Connection L/N (AC)
- Connection L/L (AC)
- Connection +/- (DC)
