Cable gland

Limited temperature range of the M20 x 1.5 plastic cable
gland for explosion protection variants.
The permissible ambient temperature range of the cable gland
is -20 ... 80 °C (-4 ... 176 °F). When using the cable gland,
make sure that the ambient temperature is within this range.
The cable gland must be installed in the housing with a
tightening torque of 3.8 Nm. When installing the connection of
the cable gland and cable, check for tightness to ensure that
the required IP rating is met.
