Incoming goods inspection
The proper and safe operation of this device
requires appropriate transport, proper storage,
installation and assembly as well as careful operation
and aintenance. When it is assumed that safe operation
is no longer possible, the device must immediately be
taken out of operation and secured against accidental
start-up.
Unpacking and packing must be carried out with
the usual care, without the use of force and only with
the use of suitable tools. The devices must be visually
inspected for proper mechanical condition.
It can be assumed that safe operation is no longer
possible if the device, e.g.
• shows visible damage,
• does not work despite intact power supply,
• and was exposed to unfavourable conditions
(e.g. storage outside of the permissible climatic
limits without adaptation to the ambient climate,
condensation, etc.) or transport stresses (e.g. falling
from a great height even without exterior visible
damage, etc.) for prolonged periods.
• Please check that the delivery is complete before you
begin with installation of the device.
CAll supplied screw terminals are attached
to the device.
About these operating instructions
These operating instructions are part of the product.
• Read the operating instructions prior to using
the device.
• Keep the operating instructions at hand throughout
the entire service life of the product and keep ready
for referencing.
• Hand over the operating instructions to each
subsequent owner or user of the product.

UMG 96RM-P/-CBM
Product description
Proper use
The UMG 96RM-P/-CBM is intended for the
measurement and calculation of electrical parameters
such as voltage, current, power, energy, harmonics etc.
in building installations, on distribution units, circuit
breakers and busbar trunking systems.
The UMG 96RM-P/-CBM is suitable for integration
into fixed and weatherproof switch panels. Conductive
switch panels must be earthed. Can be installed in any
attitude.
Measured voltage and measured current must derive
from the same network.
The measurement results can be displayed and can be
read out and further processed via the interfaces.
The voltage measurement inputs are designed for
measurements in low voltage networks, in which rated
voltages of up to 300V relative to earth and surges in
overvoltage category III can occur.
The current measurement inputs of the UMG 96RM-P/
-CBM are connected via external ../1A or ../5A current
transformers.
The measurement in medium and high voltage
networks is implemented in principle via current and
voltage transformers. The UMG 96RM-P/-CBM can be
employed both domestically and in industry.
