5.4.4 Potting the terminal box
For sensors without Ex-protection or Ex-protection zone, the terminal box can be retroactively potted.
A two-component potting compound, which can be ordered separately, is available for retroactive potting
of the terminal box on-site. Potting is only possible for sensors mounted horizontally.
Observe the following instructions when processing!
Preparation
• Connect the sensor and check that all connections are in the correct position and tight.
• Keep the potting compound away from the O-ring and seal/groove (see illustration in Fig. 41).
• Avoid the two-component potting compound penetrating the cable protection pipe in case of instal-
lation NPT 1/2" (if used).
Potting
1. Cut open the protective sleeve of the two-component potting compound (see packaging).
2. Remove the connecting clamp from the potting compound.
3. Knead the two components until fully homogenized.
4. Cut open one corner of the bag. Process the content within 30 minutes.
5. Carefully fill the two-component potting compound into the terminal box to a position over the con-
necting cable. Note the maximum filling height (4) while doing so.
6. Allow a few hours for de-gasification and drying before carefully closing the connecting lid.
7. Dispose of the packaging material and dry bag in a responsible way.
