Installation
Current measurement
The EM-PQ2500 is designed for connecting
current converters with secondary currents of
../1A and ../5A. Only alternating currents, and
no direct currents, can be measured.
Each current measurement input can be loaded
with 120A for 1 second.
Grounding current converters!
If a connection is provided for ground-
ing the secondary winding, this must be
connected with ground.
Illu. Connection example, current measurement
using current converter.
Warning!
The EM-PQ2500 is not suitable for the
measurement of direct voltages.
Warning!
The current measurement inputs are
dangerous to touch.
