(1)
Intensive sun radiation in areas of high ambient temperatures may cause inadmissible temperature rise inside
of the luminaire. This may result a decrease in lifetime of the electronic ballast (EVG). Therefore those
luminaires should be switched off during daytime by a photocell control.
(2)
The tests of clamping ranges and torque values were performed with metal mandrel. The clamping range can
vary by using cables with different manufacturing tolerances and material properties. Please use a suitable
combination of seals in the intermediate area, so that the cap nut can be tightened in future maintenance work
on the cable entry.
