4. Electrical Connections
The device may only be operated
in one of the connection options
shown below!
Supply
Voltage direct Current direct
Current via current transformer Voltage, current via current transformer
Voltage, current on high side
50V max!
Current on high side
50V max!
Warning:
Voltage measurement on the high side (between plus and load) is
recommended only for voltages up to 50V!
In this case the entire device is on high potential. Particularly to be considered
when connecting switches to JP1-6.
