Electrical Connection - IFM Electronic efector160 LI5 Bedienungsanleitung

• When several LI5 units are mounted in one tank minimum
distances between them must be maintained. These depend on the
medium and the respective application.
Approximate values for common media:
Water / coolant emulsions in a grounded metal tank
Oils in a grounded metal tank
Water, hydrous media and oils in a small plastic tank
(ungrounded)
*Distance from the centreline of a probe to the centreline of ano-
ther probe. The approximate values refer to standard operating
conditions. Depending on the application greater distances can be
required. Check this by means of a realistic function test (→
"5. Installation and set-up / operation").
• Distance between sensors type LI5xxx and LKxxxx: min. 60 mm from
the centreline of a probe to the centreline of another probe.

3. Electrical connection
