9. MOUNTING AND INSTALLATION
Mounting and installation of light fitting is carried out according to the labeled technical data and the additional
manufacturer's instructions, national rules and regulations, as well as the generally recognized rules of technique. Only
under this conditions the explosion protection that is committed with type certificate will be confirmed.
The quality of the used materials ensures compliance in the “standard” industrial atmosphere. For special requirements
please contact the manufacturer.
Standard mounting is performed with suspension or fixing with a screws through an Ø13 mm hole in the housing. Using
accessories for quick installation FLXE 20-170 can be directly fixed on the wall or ceiling - screw accessories Ø8 at a
distance of 230 mm. Using accessories for quick installation FLXE 20-180 can be directly fixed on the pole with
diameter up to 2".
Ex d cable glands and EX d plugs are not part of the standard delivery for the types FLX 310 LED/0 and
310 FLX LED/1, but it’s ensured users. Standard design lamps presumed closure introduction with blind introductions
to protect volumes. When installing the user should comply with the cable glands manufacturer instructions. If the user
requests through-wiring, it is necessary to use two Ex de adapter or two Ex d glands
The light fitting comes with a cover fully twisted in its entirety in the housing and mechanically locked by a screw
M5x10 ISO 4027to protect from self-loosening. After each opening, lamp threat should be protected by protective agent
threads.
Checking individual traceability of the quality control plan.
Testing the insulation resistance at 10 MW / 500 V DC.
Testing of mechanical strength of the casing with static pressure 1,5P
Testing dielectric strength between L / N short circuit and with test voltage (2UN + 1000 V) rms ie. 1500 V r.m.s.
for min. 60 or the test voltage of 1.2 (2UN + 1000 V) rms ie. 1800 V r.m.s. for min. 100 ms.
for at least 10s.
