10.1 Installation conditions and cable glands
The integral mount version of the CT transmitter in the SG1 housing is to be installed in accordance with
Section 3.5.1 Installation on page 18. If the CT transmitter is installed separately, a vibration-free installa-
tion site must be ensured.

They are not contained in the scope of supply. The operator is responsible for
the fact that according to the enclosure and ignition enclosure certified cable
glands or screws are used. The kind of the thread is stamped on the rating
plate.
At the connection between sensor and transmitter a metalized cable gland
must be used for the screen.
