following instructions:
Dispose of packing material properly.
Do not place the ballast into operation if damages are apparent.
To assure safe operation, use EB only according to the information given in these
operating instructions, connect it as shown on the serial number plate.
In case of malfunction, disconnect the EB from mains (pull out the line plug).
Repairs, exchange of replacement parts and manipulations on the EB must be carried

3. Product Description
The Electronic Ballast ARRI EB 1200/1800 Event Three is part of an optimized lighting
system along with a suitable multicore cable system and up to three luminaires (see
fig.1, page 16).
The ARRI EB 1200/1800 Event Three consists of 3 modules (see fig.3, page 17). Each
modul can drive one 1200 W or 1800 W luminaire.
The ballast is suitable for professional indoor use (IP20 protection).
Compared to magnetic ballasts there are a number of advantages when operating
daylight-lamps with ARRI Electronic Ballasts:
No synchronization of cameras necessary
Typical lightripple max. 3 %
Light intensity increased by at least 5 %
Constant lamp power
Constant color temperature
Constant light quality
Control of electric power of the lamp between 50...105%
Variation in power supply voltage of 10% has no influence on the power of the lamp
(see also "Technical Data" for limits, on page 14).
Variation in power supply frequency of 10% has no influence on the power of the
lamp
Operating lifetime of the lamp increased by at least 20%
Substantially less volume and weight compared to magnetic ballasts
CCL (Compensation of Cable Losses)
Compensates the electric losses in the cables between ballasts and lamphead by
automatic increase of output power . With 1800 W lampheads compensation is done
for losses up to the lamphead, with 1200 W lampheads for losses up to the splitbox.
