LECTRICAL CONNECTION
The ultrasonic level meter is designed to be connected to supply unit or to controller through two
or three-wire cable with outer diameter 6 ÷ 8 mm (recommended cross section of cores 0.5 mm
to 0.75 mm
) by means of connector which is included in delivery. Connection diagram and inner
2
view of the connector as shown in
Fig. 14 and 15.
Make the electric connection in
voltage-free state.
Note: In case of strong electromag-
netic interferences (EMI), parallel
cable ducting with power lines, or
when cable length exceeds 30 m
we recommended to use shielded
cable.
WARNING:
With regard to possible occurrence
of electrostatic charge on non-
conductive parts of the level meter,
metallic fl anges of the ULM–53Xi–10
and 20 (for explosive areas) level me-
ters must be grounded with ground
terminal!
