7.2.2 Special Points to Note When Using the Device in Explosion-proof Areas
The following applies when using the F200K Ex-II, F200K Ex in explosion-proof areas:
• For use only in approved explosion protection zones.
• To protect its aperture, only mount the F200K Ex-II, F200K Ex on a burner or boiler using
one of its holders: the FV30, FH30 or FS50.
• Use only the types of cable specified by the manufacturer when extending cables.
• When extending cables in the potentially explosive area, use only terminal housings that
are approved for this area. LAMTEC recommends the connection housing FG24 Ex for
this purpose.
• Check if cable connections fit tightly. Should there be a need to loosen the cable connec-
tion, it is to be ensured that the cables do not turn while loosening and tightening the cable
connection.
• Note, in particular, the information on setup in EN 60079-14, section 12.2 (cables and

Instructions for procedures to work safely in an explosive gas atmosphere', only permitted
after the release by personnel in charge of the explosion protection of the operating
company.
• Opening the device is required during commissioning!
Should there be any risk of danger to the surroundings in an opened device, a clearance
measurement as described above should be done before the opening.
• A transformer for generating the supply voltage must be carried out according to
IEC 61558-2-6.
• You must use a current limiter with a limit on the rated voltage.
• When using the device in the ambient temperature range, you must keep the temperature
in accordance with the temperature class:
See Ex marking on the device
• If devices are so damaged that they no longer meet the requirements of the protection
class, you must replace them.
