UMG 512

Residual current measurement inputs (RCM)

The UMG 512 is suitable for use as a residual current
monitoring device (RCM) as well as for monitoring AC,
pulsing DC, and DC.

The UMG 512 can measure type A residual currents
in accordance with IEC/TR 60755 (2008-01)

.

The connection of suitable external residual current
transformers with a rated current of 30 mA is performed
via the residual current transformer inputs I5 (terminals
4/5) and I6 (terminals 6/7).

C

Residual current transformer ratio

The GridVis software included in the scope
of the delivery can be used to individually
program the residual current transformer
inputs' transformer ratios.
