Applying the measuring current
The UMG96S is designed for the connection of
../1A and ../5A current transformers.
Only alternating currents, not direct currents,
can be measured via the current measurement
inputs.
Current transformer terminals must be
earthed on the secondary side.
Current transformers, which are not
loaded on the secondary side can con-
duct dangerous contact voltages and
therefore must be short-circuited.
Individually connect the current measurement
inputs and compare the current displayed by
the UMG96S with the applied current. Take into
account that the current transformer ratio is set
to 5/5A in the factory and may need adjusting
to the current transformers used.
If the current converter is short-circuited on the
secondary side, the UMG96S must display zero
amperes in the corresponding phase conduc-
tor.
Taking into account the current transformer, the
current displayed by the UMG96S must corre-
spond to the input current.
Checking the phase assignment
The assignment of the phase conductor to the
current transformer is correct if you short-circuit
a current transformer on the secondary side
and the current displayed by the UMG96S in
the corresponding phase drops to 0A.
