CONNECTION DIAGRAM

ENDA EC442 is intended for installation in control panels. Make sure that the device is used only for intended
purpose. 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.
carried on by a qualified staff and must be according to the relevant locally applicable regulations.

The shielding must be grounded on the instrument side.

Note 1) While panel mounting, additional distance required for
connection cables should be considered.

2) Panel thickness should be maximum 10mm.

3) If there is no 80mm free space at back side of the device,
it would be difficult to remove it from the panel.
