6.1.3 Special Points to Note When Using the Device in Explosion-proof Areas
The following applies when using the F300K in explosion-proof areas:
• For use only in approved explosion protection zones.
• To protect its aperture, only mount the F300K on a burner or boiler using one of its holders:
the FV30, FV40, FK41 or FK46.
• 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 FG30-20 Ex II
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
earthing).
• Only remove the connector of the F300K or FB30 Ex or any other cable connections when
it is deenergised.
See the warning on the device: WARNING – DO NOT DISCONNECT WHEN ENER-
GISED.
• In particular, seperation has to be in accordance with EN 60079-14 'Appendix: Instructions
for procedures to work safely in an explosive gas atmosphere', only permitted after the re-
lease by personnel in charge of the explosion protection of the operating company.
• The F300K and FB30 may only be opened by the manufacturer or authorized personnel.
It is not necessary to open the device when putting it into operation.
• 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 IP64 protec-
tion class, you must replace them.
Special instructions for use in Hazardous Area Class I Division 2 (valid for F300K)
• Devices shall be wired in accordance with NEC (National Electrical Code) field wiring
requirements for the location.
UL Listed Version:
• The plug of the connecting cable must be secured against self-loosening after mounting
on the flame detector. There are screws on the union nut of the connector.
