Connection Diagram
ENDA ET1412 is intended for installation in control panels. Make sure that the device is used
only for intended purpose. The electrical connections must be carried out 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 electrical power. The device must be
protected against inadmissible humidity, vibrations, severe soiling and make sure that the
operation temperature is not exceeded. The cables should not be close to the power cables or
components.
