3.4 Degree of protection
The devices meet all the requirements for IP 67.
After mounting in the field or service work, the following points have to be observed to ensure
that IP 67 protection is retained:
• Install the measuring device in such a way that the cable entries do not point upwards.
• Do not remove the seal from the cable entry.
• Remove all unused cable entries and plug them with suitable/certified drain plugs.
• Use cable entries and drain plugs with a long-term operating temperature range in
accordance with the temperature specified on the nameplate.
3.5 Post-connection check
• Are cables or the device damaged (visual inspection)?
• Does the supply voltage match the information on the nameplate?
• Do the cables used comply with the necessary specifications?
• Do the mounted cables have adequate strain relief and are they routed securely?
• Is the cable type route completely isolated? Without loops and crossovers?
• Remote version only:
- Is the flow sensor connected to the matching transmitter electronics?
- Is the connecting cable between sensor and transmitter connected correctly?
• Are all screw terminals firmly tightened?
• Have all the measures for grounding and potential equalization been correctly implemented?
• Are all cable entries installed, firmly tightened and correctly sealed?
• Cable routed as a "water trap" in loops?
• Are all the housing covers installed and securely tightened?
In addition, for measuring devices with fieldbus communication:
• Are all the connecting components (T-boxes, junction boxes, connectors, etc.) connected with
each other correctly?
• Has each fieldbus segment been terminated at both ends with a bus terminator?
• Has the max. length of the fieldbus cable been observed in accordance with the specifications?
• Has the max. length of the spurs been observed in accordance with the specifications?
• Is the fieldbus cable fully shielded and correctly grounded?

Tighten the cable entries correctly. The cables must loop down before they enter the
cable entries ("water trap").
