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.

- 3 -

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.

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.

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:

• 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

current transformers with open-circuit secondary windings!

First connect the current transformer lines to the corresponding measurement case

inputs!
