DIMENSIONS & CONNECTION DIAGRAM
ENDA EPA742 is intended for installation in control panels. Device must be used to according to instructions. Mounting 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 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.
CAUTION :
Only one of the 60mV or 5A/CT20-30 inputs can be used.
