UMG 96RM-PN
Product description
Proper use
The UMG 96RM-PN is intended for the measurement
and calculation of electrical variables such as voltage,
current, power, energy, harmonics, etc. in building
installations, on distribution units, circuit breakers and
busbar trunking systems.
The UMG 96RM-PN is suitable for integration into fixed
and weatherproof switch panels. Conductive switch
panels must be earthed.
Measured voltages and measured currents must derive
from the same network.
The measurement results can be displayed and read
out and further processed via the RS485 or ProfiNet
interface.
The voltage measurement inputs are designed for
measurements in low voltage networks where rated
voltages of up to 300V phase to earth and surge voltages
of overvoltage category III can occur.
The current measurement inputs I1-I4 of the UMG
96RM-PN are connected via external ../1A or ../5A
current transformers.
A continuous monitoring of residual currents (residual
current monitor, RCM) is performed via the current
measurement inputs I5 and I6 via an external residual
current transformer with a rated current of 30 mA.
Measurements in medium and high-voltage networks are
always performed via current and voltage transformers.

Residual current monitoring monitors residual
currents via external current transformers.
