2.6 Loop impedance (Z
s L-PE
)
1. Set function
2. Set sub-function, parameters and limits.
Z
S
Loop impedance:
Zs (for systems without RCD)
Zs rcd (for systems with RCD)
Fuse type [---, gL/gG, gG, B, C, K, D]
Nominal current of the fuse
Tripping time of the fuse
3. Connection diagrams
Connecting the plug "Commander" (044149) and the 3-wire test lead
4. Press the key .
5. The measuring result can be stored by means of the "MEM" key.
Zs ..... Loop impedance (L-PE)
Isc .... prospective short-circuit current (fault current)
Lim .. lower limiting value of the prospective short-circuit current
