36 Certification Instructions
 Units may be painted or fitted with optional accessories, some of which
are made of a 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 should
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. Cleaning of the
equipment (except window) should be done only with a damp cloth.
 The 3 fastening screws used to screw on the cover of the flameproof
compartment have a yield stress of 344N/mm
²
. Any replacement
fasteners must have a yield stress of at least this value.
 When the duct mount is fitted and the equipment is intended to be
mounted to a heated/cooled air duct/process vessel, it should be verified
that the temperature of the air duct/process vessel should not be
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.
