c
Caution!
Voltages which exceed the per-
mitted networkrated voltage
must be connected via a voltage
transformer.
c
Caution!
The UMG 96RM-E is not suitable for
measuring DC voltages.
c
Caution!
The voltage measurement inputs
on the UMG 96RM-E are dangerous
if touched!
When connecting the voltage to be measured,
the following must be observed:
Isolation device
• A suitable circuit breaker must be fitted to disconnect
and de-energise the UMG 96RM-E.
• The circuit breaker must be placed in the vicinity of
the UMG 96RM-E, be marked for the user and easily
accessible.
• The circuit breaker must be UL/IEC certified.
Overcurrent protection device
• An overcurrent protection device must be used for
line protection.
• For line protection, we recommend an overcurrent
protection device as per the technical specifications.
• The overcurrent protection device must be suitable
for the line cross section used.
• The overcurrent protection device must be UL/IEC
certified.
• A circuit breaker can be used as an isolating and line
protection device. The circuit breaker must be UL/IEC
certified.
• Measured voltages and measured currents must
derive from the same network.
