The typical leakage current of this device is max 1mA (according EN 60598-1:1996, appendix G). 2.3 Lamphead must be disconnected from Electronic Ballast and Electronic Ballast must be disconnected from mains before fitting or replacing a lamp. 2.4 The Electronic Ballast must be switched off before connecting or disconnecting either head or supply cable. Do not use other than original ARRI cables and connectors with permitted cross section of the leads. The ballast is only suitable for specified ARRI luminaires (see fig. 1, page 15). Using other than original ARRI cables or luminaires may cause injury to the user as well and/or damage to the ballast. 2.5 The Electronic Ballast satisfies the standards of the recognized state of the engineering and the pertinent safety regulation of DIN EN 60598/1:1996. 2.6 Supply voltage must not exceed the ranges that are given in the "Technical Data" (see page 13). Check that the power supply voltage and wiring are suitable for the ballast to be used. Supply voltages which are greater or less than that specified for the ballast can cause injury to the user as well as damage to the ballast. The electronic of the EB is built in a housing with protective class I and protective rate IP 20. Ambient operating temperatures must be between -10°C and + 50°C! The air slots for ventilation at front panel and rear side should never be covered or obstructed. The EB must only be placed in a 19" Cabinet Rack or on solid, flat and dry ground. Temperature of the ground should be less than 50°C. If the EB could slip over the ground it must be fastened. Protect EB against direct sunshine. The EB must be protected against splash and drip- water (acc. to protective rate IP 20). Do not operate the EB in high humidity (dew) or in aggressive or explosive gas-air mixtures. - 9 LICHTTECHNIK English 2.7 The Electronic Ballast must be used only according to the directions in this "Operating Instruction". The manufacturer shall not be liable for any damages caused by unintended use or wrong operation. 2.8 The user of the Electronic Ballast is urgently requested to observe the 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 out by a qualified personnel or ARRI service only. • Use only original spare parts for repairs. • Use only original accessories. • Make worn-out Electronic Ballasts inoperable immediately. Then dispose of the Electronic Ballast properly. • Make sure that children do not operate the EB. • Always switch off the EB and pull out line plug before you clean it or do maintenance work on it. • Clean EB dry only or with a moist cloth. Never immerse it into water. • Do not use the connection cables of the EB for carrying, do not pull them over sharp edges, clamp them under doors or clamp them in any other way. • Switch off EB when it is not needed. - 10 LICHTTECHNIK English 3. Product Description The Electronic Ballast ARRI EB 575 Event Six is part of an optimized lighting system along with up to six luminaires specified for operation with the EB (see fig.1, page 15) It is suitable for professional indoor use (IP20 protection). Note: The Electronic Ballast EB 575 Event Six meets the European Council Directive 89/336/EEC of electromagnetic compatibility. Over an extensive range limits of radio disturbance characteristic B are fulfilled. But on principle it has to be classified under characteristic A, group 1. Although limits of radio disturbance characteristic A are prescribed for industrial areas administrative authority can allow the use of equipment with characteristic A in other than industrial areas (DIN EN 55011). Compared to magnetic ballasts there are a number of advantages when operating daylight-lamps with ARRI Electronic Ballasts: • Flicker free light • 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 13). • 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 - 11 LICHTTECHNIK English 4. Start-up procedure All operating controls are arranged on the front panel (see fig. 3, page 16 ). The connectors for mains, lamps and remote control are placed on the rear panel of the EB (see fig. 2, page 15 ). 4.1 Ene...
