Potting the terminal box
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. Observe the following
instructions during work activity.
WARNING
Health hazard!
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.
Hazard warnings:
— R20: Harmful by inhalation.
— R36 / 37 / 38: Irritating to eyes, respiratory system and
skin.
— R42 / 43: May cause sensitization by inhalation and skin
contact.
Safety advice:

— 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.
Preparation
— 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. 35).
— Prevent the two-component potting compound from
penetrating the cable conduit if an NPT 1/2" installation is
used.
