7.1 Dimensions / fastening dimensions
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.

7.2 Mounting / dismounting, operating position
• Maximum tightening torque of 10 Nm for connection screw of the mounting bracket
and floodlight.
• Pendant mounting with ring eyes (M6).
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).
CAUTION
Risk of damage to the eyes caused by optical radiation!
Non-compliance can result in light injuries!
• A minimum distance of 7.751 m between the luminaire and the eye of
the viewer must be maintained for the version with narrow-beam light
distribution.
The luminaire is suitable for wall, ceiling mounting and pole mounting with a
mounting bracket.
Do not install the luminaire so that light is emitted upward and/or so that the
cable entry is pointing upward.
