janitza UMG511 Installation And Commissioning Manual page 21

When connecting the voltage measurement,
the following must be observed:
• In order to disconnect the voltage and cur-
rent, a suitable circuit breaker is to be pro-
vided.
• The circuit breaker must be positioned near
to the UMG511, identified for the user and
easy to reach.
• Only use authorised UL/IEC excess current
protection devices and circuit breakers.
• Please use a 6A (type B) cable circuit break-
er.
• The excess current protection device must
have a nominal value which is measured for
the short circuit current at the connection
point.
• Measurement voltages and measurement
currents must come from the same network.
Installation
c
Caution!
Voltages that exceed the permitted
nominal network voltages must be
connected using a voltage converter.
c
Caution!
The UMG511 is not suitable for meas-
uring DC voltages.
c
Caution!
Contact with the voltage measure-
ment inputs on the UMG511 is dan-
gerous!
c
Caution!
The voltage measurement inputs
may not be used for voltage meas-
urement in SELV circuits (low voltage
protector).
