The two-component potting compound is toxic – observe
all relevant safety measures.
Follow the Material Safety Data Sheet that are provided by
the manufacturer prior to starting any preparations.

• S24: Avoid contact with skin.
• S37: Wear suitable gloves
• S63: In case of accident by inhalation: remove casualty
to fresh air and keep at rest.
• Complete the installation before potting in order to
avoid moisture penetration. Before starting, check all
the connections for correct fitting and stability.
• Do not overfill the terminal box. Keep the potting
compound away from the O-ring and the gasket /
groove (see Fig. 29).
• Prevent the two-component potting compound from
penetrating the cable conduit if an NPT 1/2"
installation is used.
If the terminal box is to be potted subsequently on-site, a
special two-component potting compound can be
ordered separately (order no. D141B038U01). Potting is
only possible if the sensor is installed horizontally.
