Inspection on receipt
The prerequisites of faultless, safe operation of this
device are proper transport and proper storage, set-
up and installation, as well as careful operation and
maintenance. If it can be assumed that risk-free
operation is no longer possible, the device must be
immediately put out of operation and secured against
being put back into operation again.
Packing and unpacking must be carried out with
customary care without the use of force and only using
suitable tools. The devices should be visually checked
for flawless mechanical condition.
It can be assumed that risk-free operation is no longer
possible if the device, for example,
• has visible damage,
• no longer works despite the mains power supply
being intact,
• has been exposed to prolonged adverse conditions
(e.g. storage outside the permissible climate
limits without being adapted to the room climate,
condensation, etc.) or rough handling during
transportation (e.g. falling from a height, even if there
is no visible external damage, etc.).
• Please check the delivered items for completeness
before you start installing the device.
CAll screw-type terminals included in
the scope of delivery are attached to
the device.
Concerning this operation manual
This operation manual is part of the product.
• Read the operation manual before using the device.
• Keep the operation manual instructions throughout
the entire service life of the product and have them
readily available for reference.
• Pass the operation manual on to each subsequent
owner or user of the product.

UMG 96RM-PN
Product description
Proper use
The UMG 96RM-PN is intended for the measurement
and calculation of electrical variables such as voltage,
current, power, energy, harmonics, etc. in building
installations, on distribution units, circuit breakers and
busbar trunking systems.
The UMG 96RM-PN is suitable for integration into fixed
and weatherproof switch panels. Conductive switch
panels must be earthed.
Measured voltages and measured currents must derive
from the same network.
The measurement results can be displayed and read
out and further processed via the RS485 or ProfiNet
interface.
The voltage measurement inputs are designed for
measurements in low voltage networks where rated
voltages of up to 300V phase to earth and surge voltages
of overvoltage category III can occur.
The current measurement inputs I1-I4 of the UMG
96RM-PN are connected via external ../1A or ../5A
current transformers.
A continuous monitoring of residual currents (residual
current monitor, RCM) is performed via the current
measurement inputs I5 and I6 via an external residual
current transformer with a rated current of 30 mA.
Measurements in medium and high-voltage networks are
always performed via current and voltage transformers.
mResidual current monitoring monitors residual
currents via external current transformers.
The device is not an independent protective
device!
