CAUTION! Only use explosion proof or flame proof certified
materials of an appropriate IP value.
CAUTION! Unused cable entries must be sealed with an
approved threaded stopping plug. Thread type
(metric or NPT) and sizes vary; Improper installation
of cable glands, conduit or stopping plugs will
invalidate the Ex approval. If the SMV connector is
removed or is not factory installed, the entry should
be fitted with an approved flameproof stopping plug.
The temperature
rating of the glands
must be at least 20ºC
[68ºF] above
maximum operating
temperature.
Therefore, a rating of
85°C [185ºF] is
suitable for the entire
temperature range.
