For m and n , refer to the following chapter on "Cable entries".
!
Note!
Connection of remote version connecting cable Page 22
• m for the power supply cable and cable of the communications circuit, either:
– Cable entry M20 x 1.5
– Thread for cable entries ½" NPT or G ½"
• n for remote version connecting cable, either:
– Cable entry M20 x 1.5
– Thread for cable entries ½" NPT or G ½"
# Warning!
The cable entries must be sealed well.
You can find information about the cable specification in the associated Operating Instructions.
Furthermore, note the following:
• Total inductivity L  0.09 mH
cable
 0.1 μF
• Total capacitance C
cable
• Dielectric strength  500V
• Maximum line length  100m
• The transmitter (compact and remote version) must be securely integrated into the potential
equalization via the screw terminal on the exterior of the transmitter housing. Alternatively, the
compact version of the transmitter can be integrated into the potential equalization via the pipeline
as long as the pipeline provides a ground connection conforming to regulations.
• When using the remote version, the connection housing of the sensor must be grounded via the
external screw terminal. Alternatively, the sensor can be integrated into the potential equalization
via the pipeline as long as the pipeline provides a ground connection conforming to regulations.
! Note!
Further information about potential equalization, shielding and grounding can be found in the
associated Operating Instructions.
