Fuse: 0.5 A gG / BS 88 2A gG / 0.5 A class CC
Notes relating to connections:
The
Easy Config
software can also be used to select numerous other configuration variants for the types of loads and
associated network voltages.
3P – 2CT
: this connection reduces the accuracy of the phases, the current for which is worked out by vector calculation, by 0.5%.
3P – 1CT
: this connection requires a three-phase network that is perfectly balanced.
6.3.4. Connection of the functional earth
It is recommended that the functional earth be connected to guarantee optimum measuring accuracy and better emissivity/
immunity for the electromagnetic compatibility (class B in conducted emission).
