2.1 General Safety Rules for Connecting and Operating
the CT Analyzer
Observe the following general safety rules when connecting and operating the
CT Analyzer . The safety rules given here are supplemented by further notes and
warnings applicable for specific actions only. Such specific notes and warnings
are given where necessary in this user manual.
• Before putting the CT Analyzer into operation, check the test set for visible
damages.
• When taking the CT Analyzer into operation, make sure that the air slots, the
power switch and the power supply plug at the test set are not obstructed.
• Only use wires with 4mm safety "banana" connectors and plastic housing for
connection to the front panel input/output sockets.
• During the test always connect one terminal of the transformer’s primary side
to protective earth.
Warning: Make sure that the terminals of the test object to be connected to the
CT Analyzer do not carry any voltage potential. During a test, the CT Analyzer
is the only permitted power source for the test object.
Warning: Do not touch the equipment under test or the measurement leads
while the red LED on the CT Analyzer is flashing. Never connect or disconnect
measurement leads while the red LED on the CT Analyzer is flashing.
As long as the red LED is flashing, the output is active and lethal voltages can
occur due to the high energy stored in external inductors.
Warning: Always make sure that the CT Analyzer output is connected to the
correct side of the current transformer according to the wiring instructions given
in sections 2.4 to 2.5 below. Accidentally mixing up the windings can cause life-
threatening voltages within the transformer and/or destroy the connected CT
or the
CT Analyzer !
