Safety instructions:
For skilled electricians and trained
personnel in accordance with national
legislation, including the relevant
standards and, where applicable, in acc.
with IEC/EN 60079-14 on electrical
apparatus for explosive atmospheres.
– The light fitting is not suitable for use in
hazardous areas of zone 0, 1 and
zone 20, 21!
– The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered from the
user.
– The technical data indicated on the light
fitting are to be observed!
– Disconnect equipment before opening!
– Avoid powering up repeatedly for short
periods of time.
– Changes of the design and modifications
to the light fitting are not permitted!
– The light fitting shall be operated as
intended and in undamaged and perfect
condition!
– Repairs may only be carried out by CCH/
CEAG or a qualified "electrician"!
– Do not keep these operating instructions
inside the light fitting during operation!
Observe the national safety rules and
regulations for prevention of accidents
and the following safety instructions
which are marked with an (

(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 the combination of sealing 1 + 2 for the intermediate region.
(3)
When selecting the seal rubber, ensure that the pressure screw can be tightened when carrying out any future
maintenance work on the cable entry.
