NOTICE
When the enclosed threaded plug is utilized in the conduit
opening, it must be installed with a minimum thread
engagement in order to comply with explosion-proof
requirements. For straight threads, a minimum of seven
threads must be engaged. For tapered threads, a minimum of
five threads must be engaged.
Plug and seal the unused conduit connection with the
provided conduit plug.
NOTICE
To comply with EMC directive 2014/30/EU and protect against
interference caused by radio frequency interference (RFI) and
electromagnetic interference (EMI), shield the cable to the
detector and ground the detector.

3 Special conditions for use
•Lids securing fasteners shall be property class A4 with a yield
stress of 344 N/mm2.
•Units may be painted or fitted with optional accessories; some
of which are made of non-metallic material or have a non-
metallic coating which could potentially generate an ignition-
capable level of electrostatic charge under certain extreme
conditions.Therefore, these units shall not be installed in a
location where they may be subjected to external conditions
(such as high-pressure steam) which might cause a build-
up of electrostatic charges on the non-conducting surfaces.
Additionally, cleaning of the equipment should be done only with
a damp cloth.
•Temperature Increase at cable entry and branching point is
20.9°C. This needs to be considered in the selection of cables
for each ambient.
•Flameproof joints are not intended to be repaired The 40/40
Series Flame Detectors can be fitted with an unmoulded (non-
encapsulated), End of Line (EOL) Resistor. Such a resistor can only
be fitted into the flameproof ‘Ex d’ compartment as indicated in
the instructions. The EOL Resistor shall be rated at 1.56 kΩ, 1 W
minimum.
•When the duct mount is fitted and the equipment is intended
to be mounted to a heated/cooled air duct/process vessel, it
must be verified that the temperature of the air duct/process
vessel is not capable of heating or cooling any part of the
equipment enclosure to a temperature outside the marked
maximum ambient temperature range prior to switching the
equipment on, when taking into account surrounding ambient
temperature.
•The following table indicates the T-Class for each of the Ambient
Temperature:
Model Ambient (°C) T-Class T-Class
Min Max Gas Dust
40/40 D -60 +45 T6 T85 °C
-60 +60 T5 T100 °C
-60 +85 T4 T120 °C

To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following Caution and Warning
statements:
WARNING
Do not open when energized.
Do not open when an explosive atmosphere is present.
Temperature Increase at cable entry and branching point is
20.9°C. This needs to be considered in the selection of cables for
each ambient.
Potential electrostatic charging hazard – see instructions.
CAUTION
When the enclosed threaded plug is utilized in the conduit
opening, it must be installed with a minimum thread engagement
to comply with explosion-proof requirements. For straight
threads, a minimum of seven threads must be engaged. For
tapered threads, a minimum of five threads must be engaged.
Plug and seal the unused conduit connection with the provided
conduit plug.
