The ULM level meter or ULS level sensor with a C type cable gland are connected to processing (display)
units by means of a cable with an outer diameter of 4 to 6 mm (recommended wire cross-section 0.5 to
0.75 mm2), via a connector socket with a moulded cable (2 or 5 m long) or via a detachable connector
socket without a cable (see accessories). In this case connect the cable to the inner socket pins under
