Siemens SIMATIC NET SCALANCE XF-200BA Operating Instructions Manual page 37

EXPLOSION HAZARD
For operation the device is intended to be installed within an enclosure/control cabinet. The
inner temperature of the enclosure/control cabinet corresponds to the ambient temperature of
the device. Use installation wiring connections with admitted maximum operating
temperature of at least 30 °C higher than maximum ambient temperature.
If a device is operated in an ambient temperature of more than 60 to 70 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so that it
is only accessible to service personnel or users that are aware of the reason for restricted access
and the required safety measures at an ambient temperature higher than 60 °C.
Note
You must not install the device on a wall in hazardous areas.
Wall mounting outside of the control cabinet or housing does not fulfill the requirements of the
FM approval.
Wall mounting is only permitted if the requirements for the housing, the installation
regulations, the clearance and separating regulations for the control cabinets or housings are
adhered to. The control cabinet cover or housing must be secured so that it can only be opened
with a tool. An appropriate strain-relief assembly for the cable must be used.
Substitution of components may impair suitability for Division 2.
Do not remove or replace while circuit is live when a flammable or combustible atmosphere is
present.
