E) COOLING
DEB1200D ELECTRONIC BALLAST:
The sides of the housing of the electronic ballast are built as cooling elements.
Cooling ribs must not be covered or obstructed in any way. The back plate serves as
air intake and must not be covered or obstructed. The air outlets on the side vents
must allow unhindered exit of warm air.
The electronic ballast must not be operated on humid or wet surfaces.
Avoid direct sunlight on the DEB1200D.
DLH1200D DAyLIGHT FIxTURE:
To prevent the possibility of fire, the DLH1200D light head must be mounted on a
light hanger suitable for the load or on a lighting stand of suitable dimension to pre-
vent the light head from falling or tipping over.
Do not cover the air intake or air exit openings or place any object on top of the light
head.
F) REPAIR AND MAINTENANCE
Repair, maintenance and adjustments are only to be conducted by Dedotecs’ repair
department or qualified service personnel. Only manufacturers original replacement
parts are to be used.
Mains input and output of the electronic ballast are not isolated.
Extreme care must be taken when taking measurements on the ballast or light head
with power applied.
No grounded measuring instruments should be used and all relevant safety
precautions must be observed.
The ignitor produces dangerously high voltages
up to 30KV!
Disconnect head from ballast before performing the following inspection.
The high voltage cables (between the ignitor and the socket) and the sockets them-
selves must be visually inspected at least once a year (view through opened door of
the fixture). Even if only minor mechanical damage has occurred, these components
must be replaced.
Every 100 hours of operation, the lamp must be checked. Damaged or deformed
lamps must be replaced to minimize the risk of exploding lamps.
Before each operation of the system, the condition of the front lens must be checked.
A broken front lens must only be replaced by an original front lens with UV cut filter
(recognizable by a purple coloration when looked at from an angle).
