Measures for safety
When operating electrical devices certain parts 
of these devices inevitable carry dangerous 
voltages. This could result in serious bodily 
injury or damage to property if not handled 
properly:

•  Before establishing electrical connections 

to the device, earth it at the ground wire 
connection if there is one.

•  Hazardous voltages may arise in all circuit 

parts that are connected to the power supply.

•  Even after disconnecting the supply voltage, 

there may still be hazardous voltages 
present in the device (capacitor storage).

•  Do not operate equipment with current 

transformer circuits when open.

•  Do not exceed the limit values stipulated in 

the user manual and on the rating plate - even 
during testing or commissioning.

•  Observe the safety and warning information in 

the documents that belong to the devices!

In order to avoid injuries to personnel and 
property damage, only qualified personnel with 
electrical training are permitted to work on the 
devices with knowledge

•  of the national regulations for accident 

prevention

•  of safety standards
•  of installation, commissioning and operation 

of the device.

Proper use

The device is

•  intended for installation in switch cabinets 

and small installation distributors (please 
observe step 3 “Assembly”).

•  not intended for installation in vehicles! 

The use of the device in mobile equipment 
is considered to be non-standard 
environmental conditions and is therefore 
only permitted after separate agreement.

•  not intended for installation in environments 

with hazardous oils, acids, gases, vapours, 
dusts, radiation, etc.

The prerequisites of faultless, safe operation 
of this device are proper transport and proper 
storage, set-up, installation, operation and 
maintenance.

Brief description of device

Assembly

The UMG 96 RM-EL is a compact, 
multifunctional network analyser that

•  is designed for low voltage and medium 

voltage distribution systems.

•  measures and calculates electrical variables 

such as voltage, current, power, energy, 
harmonics, etc. in building installations, 
on distribution units, circuit breakers and 
busbar trunking systems.

•  displays measurement results and forwards 

them via interfaces.

•  captures the energy consumption for cost 

centre analysis.

•  is used as a measured value transducer 

for building management systems or PLC 
(Modbus).

Install the device in a weather-protected front 
panel on switching cabinets.

1.  Switch to programming mode.
2.  The symbols for programming mode 

PRG and 

for the current transformer 

CT appear.

3.  Pressing button 2 

6 times takes you to dynamic 

TCP/IP assignment (

dYn IP).

4.  Use button 1 to select the 

3rd digit (flashes).

5.  Use button 2 to select the value 

002 (DHCP).

6.  Press button 1 to confirm your setting.
7.  Exit programming mode by pressing and holding 

buttons 1 and 2 simultaneously for 1 second.

Dynamic IP assignment can also be 
carried out via the GidVis® software.

NOTE!
The key icon on the display indicates 
that dynamic TCP/IP assignment is 
active (002). The DHCP server assigns 
the TCP/IP device address, the subnet 
mask and the gateway address when 
the device starts.

The most common connections for 
communication between the PC and the device:

The PC and the UMG 96 RM-EL require a static IP address.

The DHCP server assigns IP addresses to the UMG 96 RM-EL  and 
the PC automatically.

More information on device configuration and 
communication is provided as of step 12.

Recommendation for the Ethernet connection:

Use at least CAT5 cables!

m

CAUTION!

Property damage due to 
incorrect network settings

Incorrect network settings can cause faults in 
the IT network!
Find out the correct Ethernet network 
settings for your device from your network 
administrator.

In dynamic TCP/IP assignment, (TCP/IP device 
address, subnet mask and gateway address), 
a network includes the device automatically when 
starting the device.
The dynamic TCP/IP settings are read (or assigned) 
in the same way as "manual configuration" is carried 
out (see step 12 and 15):

1.  Switch to programming mode.
2.  The symbols for programming mode 

PRG and 

for the current transformer 

CT appear.

3.  Pressing button 2 

6 times takes you to dynamic 

TCP/IP assignment (

dYn IP).

4.  Use button 1 to select the 

3rd digit (flashes).

5.  Use button 2 to select the value 

002 (DHCP).

6.  Press button 1 to confirm your setting.
7.  Exit programming mode by pressing and holding 

buttons 1 and 2 simultaneously for 1 second.

Dynamic IP assignment can also be 
carried out via the GidVis® software.

NOTE!
The key icon on the display indicates 
that dynamic TCP/IP assignment is 
active (002). The DHCP server assigns 
the TCP/IP device address, the subnet 
mask and the gateway address when 
the device starts.
