OMICRON 25
Setup and connection
3.2 Setting up CT Analyzer
Proceed as follows to set up CT Analyzer:
1. Make sure to position the CT Analyzer test set on dry, solid ground.
2. Connect the grounding terminal on the CT Analyzer’s side panel (see section 2.3 on page 15) to
protective ground (PE). Use the original cable supplied by OMICRON or alternatively a solid
connection of at least 6mm
2
. Use a ground point as close as possible to the test object.
3. Connect CT Analyzer to mains using the supplied power cord. Supply CT Analyzer only from a
power outlet that is equipped with protective ground (PE).
An error message (901) appears if the PE connection is defective or if the power supply has no
galvanic connection to ground. This can be the case in very special grid applications or if
CT Analyzer is supplied by a generator or an isolating transformer. The error message 901 is a
safety relevant message!
4. Connect the equipment under test according to the instructions given in this manual. Refer to
sections 3.4 and 3.5 for detailed descriptions how to connect CT Analyzer for a specific
measurement and/or application.
WARNING
Death or severe injury caused by high voltage or current possible
► Always make sure that protective ground and equipotential ground are connected
properly to ensure safe operation.
