Fault current monitoring
Number of meas. channels
The current transformers including the conductor isolation
must guarantee in total a reinforced or double insulation
between the mains circuit connected on the primary side and
the measuring inputs of the device.
Use only transformers intended for this application, according
to our current transformer catalog, or transformers that fulfill
the specification listed in the device handbook.
Only one measurement range may be connected per measu-
ring channel!

Safety
The current inputs are galvanically isolated from each other.
Protection class:
Pollution degree:
Protection:
The device uses the principle of protective impedance for the
voltage inputs to ensure protection against electric shock. All
circuits of the device are tested during final inspection.
Prior to performing high voltage or isolation tests involving the voltage
inputs, all output connections must be removed. A possible high-voltage
test between input and output circuits must be limited to 500V DC,
otherwise electronic components can be damaged.
