ENDA EPA942 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
