9、l. 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 connected to the AC power outlet or must be immediately disconnected by unplugging the power cable. Repairs must only be performed by

10、 trained personnel in accordance with the applicable regulations. B2Installation Site Install the unit in a place where the following conditions are met: The temperature and the relative humidity of the environment must be within the specified limits during operation of the unit. Relevant air val- u

11、es 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 OB-van), feasible measures must be taken before and after operation (for details on this subject, refer to Appendix 1). Unobstru

12、cted 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 objects placed upon them or placement of the unit on a soft support). The unit must not be heated up by external sources of heat rad

13、iation (sunlight, spot lights). B3Earthing and Power Supply Earthing of units with mains supply (class I equipment) is performed via the protective earth (PE) conductor integrated in the mains cable. Units with battery operation ( 60 V, class III equipment) must be earthed sepa- rately. Earthing the

14、 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 insulation, but may also be intro- duced by the connected audio or control cables. If the unit is installed with one or several

15、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.g. by pulling the mains plug), an additional, permanent earthing must be installed using the provided earth terminal. Avoid grou

16、nd 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 current flowing through the loop by inserting an additional impedance (common-mode choke). Installation Date printed: 26.04.04 III Cl

17、ass 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 IEC320/C19) with respect to the applicable regulations in your country. Before connecting the equipment

18、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 the specifications on the equipment. Equipment supplied with a 3-pole appliance inlet (protection conformi

19、ng 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 refer to Appendix 2. Female plug (IEC320), front-side view:National American Standard: L (Live)BrownBlack N (

20、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, if one or more external signals are connected to the unit (see ex- planation at the beginning of this par

21、agraph). 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 15. The electromagnetic interference generated by the unit is limited in such a way that other equipment a

22、nd 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 standards of the speci- fied electromagnetic environment, as listed in the following declaration. The limits of

23、 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 the system are imperative prerequisites for operation without EMC problems. For this purpose, the follow

24、ing 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 installed, use only components (systems, equipment) that also fulfill the EMC stan- dards for the given environme

25、nt. Use a system grounding concept that satisfies the safety requirements (class I equipment must be connected with a protective ground conduc- Installation/Maintenance/ESD IVDate printed: 26.04.04 tor) and that also takes into consideration the EMC requirements. When deciding between radial, surfac

26、e, 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 terminal or housing should have a large surface and be corrosion-proof. Please note t

27、hat 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 as small as possible, and reduce the noise current flowing through the loop by inse

28、rting 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 keeping the relative humidity above 30%. Further meas- ures (e.g. conducting floor) a

29、re 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 allows for sufficient capacitive coupling of the operator. This coupling can be impro

30、ved 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 openings for operating elements (faders, rotary knobs) must be checked on a regular basis

31、, 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 contamination can be treated with a cloth that is slightly humidi- fied with a mild cle

32、aning 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 the unit! Liquids must never be sprayed or poured on directly! For equipment-specif

33、ic 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 handling devices sensitive to electrostatic dis- charge! Many semiconductor components

34、 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 rules when handling ESD sensitive components: ESD sensitive components should only

35、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 packing ESD/Repair Date printed: 26.04.04 V material in which the replacement asse

36、mbly 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 bench) and only be touched by persons who wear a wristlet that

37、 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- nected to this ground potential. The terminals of ESD sensitiv

38、e 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 inadmissible voltages or compensation currents, electri- cal con

39、nections 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 precautions must be observed: Maintenance may only be performed by

40、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, parts with hazardous charges (e.g. capacitors, picture tube

41、s) 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-insulated circuit components and metallic semiconductor housi

42、ngs 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 polarity. Do not short battery terminals. Replace batteries only

43、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 components should only be handled by trained personnel who are prop

44、erly protected (e.g. safety goggles, gloves). Repair/Disposal VIDate printed: 26.04.04 E1SMD Components Studer does not keep any commercially available SMD components in stock. For repair the corresponding devices should be purchased locally. The specifications of special components can be found in

45、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. FDisposal Disposal of Packing MaterialsThe p

46、acking 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 to use recyclable means. Disposal of

47、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 can be recycled is. Please take care

48、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 Com
