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

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!
