ENDA EPV241A 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. Make sure that the operation temperature is
not exceeded. The cables should not be close to the power cables or components.

CONNECTION DIAGRAM
ENDA EPV541 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.
