The UMG 96 RM-E  is a multi-functional net-
work analyser, which

•  measures and monitors residual currents 

(RCM) and currents at the central grounding 
point (CGP). The residual current monitoring 
is carried out via an external residual current 
transformer (30 mA rated current) on the 
current measurement inputs I5 and I6.

•  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 and saves measurement results 

and transmits them via interfaces.

Install the UMG 96 RM-E in the weather-protected 
front panel of switch cabinets.

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!

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!

•  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.

C

NOTE!
If residual currents in electrical systems 
are monitored, the device (inputs I5/I6) 
can trigger warning pulses if a response 
threshold is exceeded. The warning pulses 
can provide an alarm before a protective 
device trips. 
The device does not provide protection 
against electric shock!

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!

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.

C

NOTE!
If residual currents in electrical systems 
are monitored, the device (inputs I5/I6) 
can trigger warning pulses if a response 
threshold is exceeded. The warning pulses 
can provide an alarm before a protective 
device trips. 
The device does not provide protection 
against electric shock!

m

CAUTION!

Damage to property due to 
disregard of the installation 
instructions

Disregard of the installation instructions can 
damage or destroy your device.

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!

•  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.

C

NOTE!
If residual currents in electrical systems 
are monitored, the device (inputs I5/I6) 
can trigger warning pulses if a response 
threshold is exceeded. The warning pulses 
can provide an alarm before a protective 
device trips. 
The device does not provide protection 
against electric shock!

m

CAUTION!

Damage to property due to 
disregard of the installation 
instructions

Disregard of the installation instructions can 
damage or destroy your device.

Manual TCP/IP configuration via the Ethernet interface

Within an Ethernet network, each device has a unique 
TCP/IP address that can be assigned manually or from 
a DHCP server.
The 4-byte-long device address (Byte 0 to 3) is 
appended within the TCP/IP configuration with the 
subnet mask and gateway details.
Manual configuration (example) of the TCP/IP 
device address (Addr):

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

PRG, and for 

the current transformer 

CT appear.

3.  Pressing button 2 three times takes you to the 

TCP/IP settings.

With dynamic TCP/IP allocation (TCP/IP device 
address, subnet mask and gateway addresses) 
a network incorporates the device automatically 
when the device starts up.
The reading out (or the allocation) of the dynamic 
TCP/IP settings is implemented in the same way as 
the "manual configuration" (see also step 16):

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

PRG, and

"on" or "off".

6.  Confirm your selection using the 1 button.
7.  Exit programming mode by pressing buttons 1 

and 2 simultaneously for 1 sec.

The dynamic IP allocation can be implemented via 
the software.

NOTE!
The key symbol on the display indicates 
that dynamic TCP/IP allocation is active 
(

on). When the device starts up, the 

DHCP server automatically allocates the 
TCP/IP device address, subnet mask 
and gateway address.
