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.
mResidual current monitoring monitors residual
currents via external current transformers.
The device is not an independent protective
device!

UMG 96RM-PN
Measuring process
The UMG 96RM-PN measures continuously and
calculates all effective values over a 10/12 period
interval. The device measures the real effective value
(TRMS) of the voltages and currents connected to
the measurement inputs.
Operating concept
You can program and call up the measured values via
many routes using the UMG 96RM-PN.
• Directly on the device via 2 buttons.
• Using the GridVis programming software.
• Using the device homepage (no programming).
• Using the Modbus protocol.
You can modify and call up the data using
the Modbus address list. The list can be called up
via the device's home page and can be found on
the enclosed CD.
• Using the PLC within a PROFINET environment.
This operation manual only describes how to operate
the UMG 96RM-PN using the two buttons.
The GridVis programming software has its own "online
help" system.
GridVis network analysis software
The UMG 96RM-PN can be programmed and read out
using the GridVis network analysis software (Download:
www.janitza.com). For this, a PC must be connected to
the UMG 96RM-PN via a serial interface (RS485) or by
ethernet.

Position of installation
The UMG 96RM-PN is suitable for integration into fixed
and weatherproof switch panels. Conductive switch
panels must be earthed.
Mounting position
To ensure adequate ventilation, the UMG 96RM-PN
must be installed vertically. There should be separation
above and below of at least 50mm with 20mm space to
the sides.

Mounting
The UMG 96RM-PN is secured in the switchboard
by the mounting clips on the side. Before insertion
the device they must be removed, for example by using
a screwdriver to lever them horizontally.
Fig. Side view of
the UMG 96RM-PN with
mounting clip.
To release the clips, use
a screwdriver to lever
them horizontally.
Mounting is then performed by sliding in and engaging
the clips and subsequently screwing in the screws.
• Screw in the clamping screws until they are just
touching the mounting plate.
• Tighten the clamping screws by two more turns
each (tightening the screws too far can destroy
the mounting clips).

cAttention!
The voltage measurement inputs on
the UMG 96RM-PN are dangerous if
touched!
When connecting the voltage to be measured,
the following must be observed:
