6 Transport and storage
• Transport and store the device only in the original packaging.
• Store the device in a dry place (no condensation) and vibration-free.
• Do not drop the device.
7 Mounting and installation
DANGER
Explosion hazard due to incorrect installation of the device!
Non-compliance results in severe or fatal injuries.
• Carry out installation strictly according to the instructions and national
safety and accident prevention regulations to maintain the explosion
protection.
• Select and install the electrical device so that explosion protection is not
affected due to external influences, i.e. pressure conditions, chemical,
mechanical, thermal and electric impact such as vibration, humidity and
corrosion (see IEC/EN 60079-14).
• The device must only be installed by trained qualified personnel who is
familiar with the relevant standards.
NOTICE
Malfunction or device damage caused by condensation.
Non-compliance can result in material damage!
• operate the luminaire continuously or periodically over extended periods of time.
• avoid thermal bridges.

DANGER
Explosion hazard due to inadmissible heating!
Non-compliance results in severe or fatal injuries.
• Avoid external heat sources and/or direct sunlight
(risk of change of temperature class or change of maximum permissible
surface temperature).
• Do not exceed the maximum ambient temperature due to external heat
sources (premature failure of equipment).
NOTICE
Risk of overheating due to high thermal radiation!
Non-compliance can result in material damage!
• Maintain a minimum distance of 0.5 m to the lighting object.
The light fitting is suitable for wall and ceiling mounting.
