Safety information
Please read the operating instructions enclosed
diligently, as well as all other publications that
must be drawn upon for working with this
measurement case and the accessories.
Observe all safety instructions and warnings.
Failure to comply with the instructions can result
in personal injuries and/or damage to the product.
The measurement case must only be operated by
specialised personnel. Specialised personnel are
persons, that based on their respective training
and experience, are qualified to recognise risks
and prevent potential dangers that can be
caused by the operation or maintenance of the
measurement case.
Check the measurement case, the measurement
wires and accessory parts for any signs of
damage before use. Check whether there are
cracks in the plastic of any parts missing. Pay
particular attention to the insulation of the wiring
and connectors. Defective parts must be replaced
immediately. Do not use if damaged!
Comply with all of the locally applicable and
national safety regulations.
Use personal protective equipment (e.g. approved
rubber gloves, face protection and protective
clothing) in order to avoid electric shocks and
burning injuries.
If the measurement case is not operated in
accordance with the operation manual, protection
is no longer ensured and hazards can be
presented by the device!
Do not work with the device if the front plate
has been removed. Otherwise, you may come
into contact with hazardous voltages! It is not
permitted to use the device with the front plate
removed!
The UMG 96RM-E is not suitable for
measuring DC voltages.
Measured voltages and measured
currents must derive from the same
network. Voltages outside the rated
range could destroy the measurement
case.
Incorrect network settings can cause
faults in the network.

Do not use the measurement case in
wet or moist environments or in the
vicinity of explosive gases or vapours.
Use the measurement case only with
the measurement wires and adapter
supplier.
Exercise particular caution when
connecting and removing the flexible
current transformers and the gripping
probes for the measured voltage.
Ensure that the circuit to be measured
is de-energised.
Keep your fingers behind the finger
protectors on the gripping measurement
probes.
Voltages and currents that are outside
the permissible measurement range
can destroy the device.
The input voltage shall not be
higher than the rated voltage of the
measurement device.
Disconnect the input signals before
cleaning the measurement case.
c
cAttention! Fatal hazard due to electrical energy:
High voltage spikes that are dangerous to touch can occur on current transformers that
are driven with open-circuit secondary windings! For this reason, never operate current
transformers with open-circuit secondary windings!
First connect the current transformer lines to the corresponding measurement case inputs!

Concerning this operation manual
This description and the operating instructions for
the device are part of the product.
• Read this description and the operation manual
through prior to using the device.
• Keep this description and the operation manual
throughout the complete service life of the
product and have them readily available for
reference.
• Pass this description and the operation manual
on to each subsequent owner or user of the
product.
• In the event of questions that are not covered
by this operation manual for the UMG 96RM-
E, please contact the support department of
Janitza electronics GmbH (Tel. no. +49 6441-
9642-22).
This device must only be operated and repaired
by specialised personnel.
Connecting the measurement case
1. Connect the power supply to the measurement
case (1) and connect the power supply to 230 V
/ 50 Hz.
2. Carry out basic settings on the UMG 96RM-E
(2), e.g.
- Voltage transformer / current transformer
settings
- Recording configuration or
- RCM measurement
(the transformer for RCM measurement is not
included in the scope of deliverables).
The settings can be implemented via the
accompanying GridVis software or directly
on the UMG 96RM-E (see the accompanying
instructions for the UMG 96RM-E for this).
3. Set up the measurement transformer (3) - see
"Measurement transformer configuration"
chapter.
4. Connect measured voltage with the voltage
tap-offs via the voltage inputs (4) or with the
measurement lines included in the scope of
deliverables. In doing so, observe the applicable
safety regulations.
5. Connect current transformer coils (operating
current (5) or residual current (6)) with the
measurement case via the screw terminals.
6. Connect the current transformer coils to the
consumer to be measured.
7. Measurement starts

Reading out recordings
If you wish to read out the measured data, connect
the measurement case to a PC via the Ethernet
connection (7) . The read-out is implemented via
the GridVis®software.

Measurement transformer settings
Set the following parameters at the integrated
measurement transducer:
• Compensate for the influence of the coil lengths
through the potentiometer switching (1). To do
so, set the parameters according to the table:
Measurement range DIP switch
100 A 8
250 A 7
400 A 6
630 A 5
1000 A 4
1500 A 3

• Set the current measurement range with the
DIP switch (2) in accordance with the table:
Potentiometer

• The transformer ratio should be adapted in
the UMG 96RM-E measurement device too in
accordance with the table. Change the settings
• by means of the GridVis software or
• by entries on the device (measurement
range: ratio x/1A).
Please refer to the UMG 96RM-E operation
manual for this.

CPlease ensure the correct setting of the current transformer, check the performance
values of the individual phases - these must not possess any negative signs when
drawing energy. Also check the power factor for plausibility. Turn the current
transformer if necessary!
Up to 2 residual current
measurements can be selected!
cAttention! Fatal hazard due to electrical energy:
High voltage spikes that are dangerous to touch can occur on current transformers
that are driven with open-circuit secondary windings! For this reason, never operate
