PLEASE NOTE!!!
The dedolight LED lighting system (DLED) is an instrument for professional use. Please read this manual carefully.
During operation the luminaire (light head) may become hot (about 90°C). These areas are marked with stickers.
Avoid long-term contact with these areas of the housing. Ensure adequate ventilation of the light head and keep a
minimum distance of 0.5m from combustible materials.
Switch the system off and unplug the AC cable before making electrical connections.
The ballast DT4 is an independent electronic control-gear for the light head DLED4. In AC versions of DT4 the
primary coils of the impulse transformer are directly connected to the mains power supply. The ballast DT4 pro-
vides Safe Extra Low Voltage (SELV). The ballast DT4 is limited power supply (LPS) type with constant current/
constant voltage output. In the light head DLED4 the voltages used are below 50V. There are no high frequencies
or electro-magnetic interferences during operation. These devices are made according to universal low-voltage
directives. A CE certificate is to be found at the end of this manual.
Electrical and electronic repairs, as well as replacement of the LED module, should be performed exclusively by
Dedo Weigert Film GmbH or an authorized representative, or a qualified and trained electrician.
