CONNECTION DIAGRAM
ENDA EPA242 is intended for installation in control panels. Make sure that the device is used only for intended purpose.The 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 electrical power. The device must be protected against
inadmissible humidity, vibrations and severe soiling. Make sure that the operation temperature is not exceeded. The cables should not
be close to the power cables or components.
