Safety information
Please read the operating instructions enclosed
diligently, as well as all other publications that
must be drawn upon for working with this
measurement case and the accessories.
Observe all safety instructions and warnings.
Failure to comply with the instructions can result
in personal injuries and/or damage to the product.
The measurement case must only be operated by
specialised personnel. Specialised personnel are
persons, that based on their respective training
and experience, are qualified to recognise risks
and prevent potential dangers that can be
caused by the operation or maintenance of the
measurement case.
Check the measurement case, the measurement
wires and accessory parts for any signs of
damage before use. Check whether there are
cracks in the plastic of any parts missing. Pay
particular attention to the insulation of the wiring
and connectors. Defective parts must be replaced
immediately. Do not use if damaged!
Comply with all of the locally applicable and
national safety regulations.
Use personal protective equipment (e.g. approved
rubber gloves, face protection and protective
clothing) in order to avoid electric shocks and
burning injuries.
If the measurement case is not operated in
accordance with the operation manual, protection
is no longer ensured and hazards can be
presented by the device!
Do not work with the device if the front plate
has been removed. Otherwise, you may come
into contact with hazardous voltages! It is not
permitted to use the device with the front plate
removed!
The UMG 512 is not suitable for
measuring DC voltages.
Measured voltages and measured
currents must derive from the same
network. Voltages outside the rated
range could destroy the measurement
case.
Incorrect network settings can cause
faults in the network.

Do not use the measurement case in
wet or moist environments or in the
vicinity of explosive gases or vapours.
Use the measurement case only with
the measurement wires and adapter
supplier.
Exercise particular caution when
connecting and removing the flexible
current transformers and the gripping
probes for the measured voltage.
Ensure that the circuit to be measured
is de-energised.
Keep your fingers behind the finger
protectors on the gripping measurement
probes.
Voltages and currents that are outside
the permissible measurement range
can destroy the device.
The input voltage shall not be
higher than the rated voltage of the
measurement device.
Disconnect the input signals before
cleaning the measurement case.

Attention! Fatal hazard due to electrical energy:
High voltage spikes that are dangerous to touch can occur on current transformers that
are driven with open-circuit secondary windings! For this reason, never operate current
transformers with open-circuit secondary windings!
First connect the current transformer lines to the corresponding measurement case inputs!
