• When cleaning with a damp cloth, use water or mild, non-abrasive, non-scratching
cleaning agents.
• Do not use aggressive detergents or solvents.
10.1.2 Restricted breathing test
The luminaire is equipped with a test device for restricted breathing.
Restricted breathing must be checked after installation and during regular maintenance
acc. to IEC/EN 60079-15.
Inspection according to IEC/EN 60079-15, para. 23.2.3.2.1.1
In order to test restricted breathing (pressure test), the luminaire is equipped with a cable
entry with red stopping plugs.
• Remove the red stopping plug.
• Insert the hose of the test device into the cable entry for testing restricted breathing.
• Hand-tighten the cable entry.
• Use the hand pump to create a vacuum of 0.3 kPa (3 mbar).
The test has been passed if after 90 seconds a vacuum of at least 0.15 kPa (1.5 mbar)
is still present in the luminaire.
