Residual current measurement (RCM) via I5, I6
The UMG 96RM-E is for use as a residual current
monitoring device (RCM), suitable for monitoring AC,
pulsing DC, and DC.
The UMG 96RM-E can measure residual currents
in accordance with IEC/TR 60755 (2008-01)
of type A and
type B.
The connection from suitable external residual current
transformers with a rated current of 30 mA is done via
the residucal current transformer inputs I5 (terminals
33/34) and I6 (terminals 36/37).
