3.1 General safety rules for connecting and operating
the CT Analyzer
Observe the following general safety rules and the safety instructions given in chapter 1 "Safety
instructions" on page 4 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 m
anual.
► 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 and that the test set can be easily disconnected
from mains.
► 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
Death or severe injury caused by high voltage or current possible
► 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
Death or severe injury caused by high voltage or current possible
As long as the red LED on the CT Analyzer is flashing, the output is active and lethal
voltages can occur due to the high energy stored in external inductors.
► 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.
WARNING
Death or severe injury caused by high voltage or current possible
Accidentally mixing up primary and secondary windings can cause life-threatening
voltages and/or destroy the connected CT or the CT Analyzer.
► 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 the CT Analyzer User
Manual.
