5.2 Electrical mounting

Cable glands
Requirements for meeting ingress protection:
Only use cable glands within their indicated clamping area (cable diameter suitable for
■
the cable gland).
Do not use the lower clamping area with very soft cable types.
■
Only use round cables (if necessary, slightly oval in cross-section).
■
Do not twist the cable.
■
Repeated opening/closing is possible; however only if necessary, as it might have a
■
detrimental effect on the ingress protection
For cables with a pronounced cold-flow behaviour the screw connection must be fully
■
tightened.

5.3 Electrical connection

CAUTION!
Danger of short circuit
Damage to cables, wires and connection points can lead to malfunction of
the instrument.
▶ Avoid damaging the cables and wires.
▶ Fine-stranded leads with bare ends must be finished with end splices
(cable preparation).
▶
Both the internal effective capacitance and inductance must be
considered.
The electrical connection is to be made according to the following sensor connections/
pin assignments.

The installation of the measuring insert is carried out in
the reverse order (clean the measuring insert prior to
installation).
The hexagonal crimped tip of the measuring insert is
guided by the screw-in of the hexagonal socket screw.
Tightening torque of the screw: 12 ... 14 Nm
