Installation
The following has to be considered when con-
necting the voltage measurement:
•
A suitable separator is to be provided in order
to disconnect the EM-PQ2500 from the cur-
rent and voltage.
•
The separator must be placed near to the
EM-PQ2500, labelled for the user and must
be easy to reach.
•
Use UL/IEC authorized overcurrent protection
and isolators (10A type C) only.
•
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
EM-PQ2500 are dangerous to touch!
c
Warning!
The EM-PQ2500 is not suitable for
measuring 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).
