Note!
• Use a connecting cable with a continuous operation temperature between –40 °C (–40 °F)
and the max. permitted ambient temperature plus 10 °C (plus 18 °F).
• Conductor cross-section: max. 2.5 mm² (14 AWG)
• A shielded connecting cable must be used.
• Route the connecting cable so it is securely seated.
• Pay particular attention to company-internal grounding concepts and national installation
regulations and guidelines.
• Seal the cable entries and covers tight.
"
Caution!
Risk of damaging the electronic components!
Connect the connecting cable
in accordance with the connection data on the nameplate or
the connection data in the Operating Instructions or the Ex documentation on the CD-ROM.
In addition, for the remote version:
"
Caution!
Risk of damaging the electronic components!
• Only connect sensors and transmitters with the same serial number.
• The remote version must be grounded. In doing so, the sensor and transmitter must be
connected to the same potential matching.
• Observe the cable specifications of the connecting cable
Operating Instructions on the
CD-ROM.
!
Note!
Install the connecting cable securely to prevent movement.
In addition, for measuring devices with fieldbus communication:
"
Caution!
Risk of damaging the electronic components!
• Observe the cable specification of the fieldbus cable
Operating Instructions on the
CD-ROM.
• Keep the stripped and twisted lengths of cable shield as short as possible.
• Screen and ground the signal lines
Operating Instructions on the CD-ROM.
• If the shielding of the cable is grounded at more than one point in systems without additional
potential equalization, power supply frequency equalization currents can occur that damage
the cable or the shielding. In such instances, the shielding of the cable only has to be grounded
on one side. This means that it may not be connected to the ground terminal of the housing.
The shield that is not connected should be insulated!
