9、tion Hints Please consider besides these general hints also any product-specific hints in the Installation chapter of this manual. B1Unpacking Check the equipment for any transport damage. A unit that is mechanically damaged or that has been penetrated by liquids or foreign objects must not be conne

10、cted to the AC power outlet or must be immediately disconnected by unplugging the power cable. Repairs must only be performed by trained personnel in accordance with the applicable regulations. B2Installation Site Install the unit in a place where the following conditions are met: The temperature an

11、d the relative humidity of the environment must be within the specified limits during operation of the unit. Relevant air val- ues are the ones at the air inlets of the unit. Condensation must be avoided. If the unit is installed in a location with large variation of ambient temperature (e.g. in an

12、OB-van), feasible measures must be taken before and after operation (for details on this subject, refer to Appendix 1). Unobstructed air flow is essential for proper operation. Air vents of the unit are a functional part of the design and must not be blocked in any way during operation (e.g. by obje

13、cts placed upon them or placement of the unit on a soft support). The unit must not be heated up by external sources of heat radiation (sunlight, spot lights). B3Earthing and Power Supply Earthing of units with mains supply (class I equipment) is performed via the protective earth (PE) conductor int

14、egrated in the mains cable. Units with battery operation ( 60 V, class III equipment) must be earthed sepa- rately. Earthing the unit is one of the measures for protection against electrical shock hazard (dangerous body currents). Hazardous voltage may not only be caused by a defective power supply

15、insulation, but may also be intro- duced by the connected audio or control cables. If the unit is installed with one or several external connections, its earthing must be provided during operation as well as while the unit is inoperative. If the earthing could be interrupted via the power supply (e.

16、g. by pulling the mains plug), an additional, permanent earthing must be installed using the provided earth terminal. Avoid ground loops (hum loops) by keeping the loop surface as small as possible (by consequently guiding the earth conductors in a narrow, paral- lel way), and reduce the noise curre

17、nt flowing through the loop by inserting an additional impedance (common-mode choke). Installation III Class I Equipment (Mains Operation) Should the equipment be delivered without a matching mains cable, the latter has to be prepared by a trained person using the attached female plug (IEC320/C13 or

18、 IEC320/C19) with respect to the applicable regulations in your country. Before connecting the equipment to the AC power outlet, check that the local line voltage matches the equipment rating (voltage, frequency) within the admissible tolerance. The equipment fuses must be rated in accordance with t

19、he specifications on the equipment. Equipment supplied with a 3-pole appliance inlet (protection conforming to class I equipment) must be connected to a 3-pole AC power outlet so that the equipment cabinet is connected to the protective earth. For information on mains cable strain relief please refe

Female plug (IEC320), front-side view:National American Standard: L (Live)BrownBlack N (Neutral)BlueWhite PE (Protective EarthGreen/YellowGreen Class III Equipment (Battery Operation up to 60 VDC) Equipment of this protection class must be earthed using the provided earth terminal,

21、if one or more external signals are connected to the unit (see ex- planation at the beginning of this paragraph). B4Electromagnetic Compatibility (EMC) The unit conforms to the protection requirements relevant to electromag- netic phenomena that are listed in the guidelines 89/336/EC and FCC, part 1

22、5. The electromagnetic interference generated by the unit is limited in such a way that other equipment and systems can be operated normally. The unit is adequately protected against electromagnetic interference so that it can operate properly. The unit has been tested and conforms to the EMC standa

23、rds of the speci- fied electromagnetic environment, as listed in the following declaration. The limits of these standards ensure protection of the environment and cor- responding noise immunity of the equipment with appropriate probability. However, a professional installation and integration within

24、 the system are imperative prerequisites for operation without EMC problems. For this purpose, the following measures must be followed: Install the equipment in accordance with the operating instructions. Use the supplied accessories. In the system and in the vicinity where the equipment is installe

25、d, use only components (systems, equipment) that also fulfill the EMC stan- dards for the given environment. Use a system grounding concept that satisfies the safety requirements (class I equipment must be connected with a protective ground conduc- Installation/Maintenance/ESD IV tor) and that also

26、takes into consideration the EMC requirements. When deciding between radial, surface, or combined grounding, the advan- tages and disadvantages should be carefully evaluated in each case. Use shielded cables where shielding is specified. The connection of the shield to the corresponding connector te

27、rminal or housing should have a large surface and be corrosion-proof. Please note that a cable shield connected only single-ended can act as a transmitting or receiving an- tenna within the corresponding frequency range. Avoid ground loops or reduce their adverse effects by keeping the loop surface

28、as small as possible, and reduce the noise current flowing through the loop by inserting an additional impedance (e.g. common- mode choke). Reduce electrostatic discharge (ESD) of persons by installing an appro- priate floor covering (e.g. a carpet with permanent electrostatic fila- ments) and by ke

29、eping the relative humidity above 30%. Further meas- ures (e.g. conducting floor) are usually unnecessary and only suitable if used together with corresponding personal equipment. When using equipment with touch-sensitive operator controls, please take care that the surrounding building structure al

30、lows for sufficient capacitive coupling of the operator. This coupling can be improved by an additional, conducting surface in the operators area, connected to the equipment housing (e.g. metal foil underneath the floor covering, carpet with conductive backing). CMaintenance All air vents and openin

31、gs for operating elements (faders, rotary knobs) must be checked on a regular basis, and cleaned in case of dust accumula- tion. For cleaning, a soft paint-brush or a vacuum cleaner is recommended. Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft brush. Persistent cont

32、amination can be treated with a cloth that is slightly humidi- fied with a mild cleaning solution (soap-suds). For cleaning display windows, commercially available computer/TV screen cleaners are suited. Use only a slightly damp (never wet) cloth. Never use any solvents for cleaning the exterior of

33、the unit! Liquids must never be sprayed or poured on directly! For equipment-specific maintenance information please refer to the corre- sponding chapter in the Operating and Service Instructions manuals. DElectrostatic Discharge during Maintenance and Repair Caution: Observe the precautions for han

34、dling devices sensitive to electrostatic dis- charge! Many semiconductor components are sensitive to electrostatic discharge (ESD). The life-span of assemblies containing such components can be drastically reduced by improper handling during maintenance and repair work. Please observe the following

35、rules when handling ESD sensitive components: ESD sensitive components should only be stored and transported in the packing material specifically provided for this purpose. When performing a repair by replacing complete assemblies, the re- moved assembly must be sent back to the supplier in the same

36、 packing ESD/Repair V material in which the replacement assembly was shipped. If this should not be the case, any claim for a possible refund will be null and void. Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g. area for field service, repair or service be

37、nch) and only be touched by persons who wear a wristlet that is connected to the ground potential of the repair or service bench by a series resistor. The equipment to be repaired or serviced as well as all tools and electri- cally semi-conducting work, storage, and floor mats should also be con- ne

38、cted to this ground potential. The terminals of ESD sensitive components must not come in uncon- trolled contact with electrostatically chargeable (voltage puncture) or metallic surfaces (discharge shock hazard). To prevent undefined transient stress of the components and possible damage due to inad

39、missible voltages or compensation currents, electri- cal connections should only be established or separated when the equipment is switched off and after any capacitor charges have decayed. ERepair Removal of housing parts, shields, etc. exposes energized parts. For this reason the following precaut

40、ions must be observed: Maintenance may only be performed by trained personnel in accordance with the applicable regulations. The equipment must be switched off and disconnected from the AC power outlet before any housing parts are removed. Even if the equipment is disconnected from the power outlet,

41、 parts with hazardous charges (e.g. capacitors, picture tubes) must not be touched until they have been properly discharged. Do not touch hot components (power semiconductors, heat sinks, etc.) before they have cooled off. If maintenance is performed on a unit that is opened and switched on, no un-i

42、nsulated circuit components and metallic semiconductor housings must be touched, neither with your bare hands nor with un-insulated tools. Certain components pose additional hazards: Explosion hazard from lithium batteries, electrolytic capacitors and power semiconductors (watch the components polar

43、ity. Do not short battery terminals. Replace batteries only by the same type). Implosion hazard from evacuated display units. Radiation hazard from laser units (non-ionizing), picture tubes (ioniz- ing). Caustic effect of display units (LCD) and components containing liquid electrolyte. Such compone

44、nts should only be handled by trained personnel who are properly protected (e.g. safety goggles, gloves). Repair/Disposal VI E1SMD Components Studer does not keep any commercially available SMD components in stock. For repair the corresponding devices should be purchased locally. The specifications

45、of special components can be found in the service man- ual. SMD components should only be replaced by skilled specialists using ap- propriate tools. No warranty claims will be accepted for circuit boards that have been damaged. Proper and improper SMD soldering joints are illus- trated below. FDispo

46、sal Disposal of Packing MaterialsThe packing materials have been selected with environmental and disposal issues in mind. All packing material can be recycled. Recycling packing saves raw materials and reduces the volume of waste. If you need to dispose of the transport packing materials, please try

47、 to use recyclable means. Disposal of Used EquipmentUsed equipment contains valuable raw materials as well as materials that must be disposed of professionally. Please return your used equipment via an authorized specialist dealer or via the public waste disposal system, en- suring any material that

48、 can be recycled is. Please take care that your used equipment cannot be abused. To avoid abuse, delete sensitive data from any data storage media. After having dis- connected your used equipment from the mains supply, make sure that the mains connector and the mains cable are made useless. 32 Dismounting MountingExamples Solder SMD Component Copper Track Adhesive Soldering Iron Desoldering Iron Desolder Wick Heat and RemoveCleaning Solder 0.5.0.8 mm Heating Time 3 s per Side Soldering Iron Desolder Wick
