“56” on terminal (11), see section “Electrical connec-
tions - Connection of sensors and external units”.
If a conduit is used it must be sealed to prevent con-
densation in the sensor capsule. The minimum cable
cross section should be 0.4 mm
2 up to lengths of 50
metres, for example, EKKX or LiYY.
