should not be connected to the input terminals. Otherwise, the device will be broken down. To change the input type from
voltage to a current measurement mode while the device is operating, first, leave out the voltage inputs. Then, change
input type to one of the current measurement modes.

CONNECTION DIAGRAM
ENDA EI7412 is intended for installation in control panels. Make sure that the device is used only for intended purpose. The shielding must be
grounded on the instrument side. During an installation, all of the cables that are connected to the device must be free of energy. The device
must be protected against inadmissible humidity, vibrations, severe soiling and make sure that the operation temperature is not exceeded. All
input and output lines that are not connected to the supply network must be laid out as shielded and twisted cables. These cables should not be
close to the power cables or components. The installation and electrical connections must be carried on by a qualified staff and must be
according to the relevant locally applicable regulations.
