UMG 508
The following has to be considered when con-
necting the voltage measurement:
• A suitable separator is to be provided in order
to disconnect the UMG508 from the current
and voltage.
• The separator must be placed near to the
UMG508, labelled for the user and must be
easy to reach.
• Use for over current protection and circuit
breaker an UL/IEC approved fuse 10A Class
CC.
• The overcurrent protection device must have
a nominal value calculated for the short-cir-
cuit current at the connection point.
• Measurement voltages and measurement
currents must come from the same network.
Warning!
The voltage measurement inputs on the
UMG508 are dangerous to touch!
c
Warning!
The UMG508 is not suitable for measu-
ring DC voltages.
Warning!
Voltages that exceed the authorized
network nominal voltages must be
connected using a voltage converter.
c
Warning!
The voltage measurement inputs may
not be used for voltage measurement
in SELV circuits (Safety Extra Low Vol-
tage).
