IMPORTANT SAFETY NOTES

Additional installation suggestions which, from experience, reduce the effect of
electromagnetic interference:
• Make line connections as short as possible
• Use shielded lines (e.g. LIYCY 4 x 0.5 mm²)
• The cable shielding must be fitted by qualified personnel, subject to the ambient
conditions and with the aim of suppressing interference.
• Keep the unit well away from the electrical supply lines of power equipment, as well as
from any electrical or electronic equipment causing interference.
• Always connect the earthing screw of the ENS 3000 to the earthing rail (e.g. in the
control cabinet). We recommend using a cable with a diameter of 1 mm² and as short
a line length as possible.
The level switch ENS 3000 must be installed in the tank as near to vertically as possible. If
the ENS 3000 is not mounted vertically, then the accuracy of the ENS deteriorates with
increasing angle of incline. (Additional inaccuracy if ENS is at an angle of 5°: approx.
±0.5% ; additional inaccuracy if at an angle of 10°: approx. ±1.5%).
CAUTION:
The electronic level switch ENS 3000 must not be used at positive pressure. Short-
term pressure of up to 3 bar for no longer than 1 minute is possible without causing
damage.
