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.

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!

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!

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.
