CONNECTION DIAGRAM
ENDA ETI741 is intended for installation in control panels. Make sure that the device is used only for intended
purpose. The installation and electrical connections must be carried on by a qualified staff and must be according
to the relevant locally applicable regulations. During an installation, all of the cables that are connected to the
device must be free of energy. The device must be protected against inadmissible humidity, vibrations, severe
soiling and make sure that the operation temperature is not exceeded. All input and output lines that are not
connected to the supply network must be laid out as shielded and twisted cables. These cables should not be
close to the power cables or components. The shielding must be grounded on the instrument side.

thermocouple cables as shown in the figure right.
For resistance thermometer :
When 2 wired Pt 100 is used,
terminals 8 and 9 must be
