RadioFans.CN 收音机爱 好者资料库 Declaration of Conformity Application of Council directives: Standard to which Conformity is declared: 73/23/EEC (LVD) 93/68/EEC (CE mark) EN61 010-1 :1993 (Safety requirements for electrical equipment for measurement, control and laboratory use) Manufacturers Name and Address: Importers Name and Address: Type of Equipment: Component Power Supply Model No.: PRODUCT MODEL NUMBER Year of Manufacture: I, the undersigned, declare that the product specified above, when used in conjunction with the condi- tions of conformance set forth in the product instruction manual, complies with the requirements of the Low Voltage Directive 73/23/EEC, which forms the basis for application of the CE Mark to this product. Place: KEPCO Inc. 131-38 Sanford Ave. Flushing, N.Y.11352 USA Date:- 228-1348 DC-COMP/INST 062399 Saul Kupferberg (Full Name) VP OF SALES (position) A RadioFans.CN 收音机爱 好者资料库 Conditions of Conformance When this product is used in applications governed by the requirements of the EEC, the following restric- tions and conditions apply: 1. For European pplications, requiring compliance to the Low Voltage Directive, 73/23/EEC, this power supply is considered a component product, designed for built in applications. Because it is incom- plete in construction, the end product enclosure must provide for compliance to any remaining electri- cal safety requirements and act as a fire enclosure. (EN61010-1 Cl. 6, Cl. 7, CI.B, Cl. 9 and EN61010- 1 annex F) 2. This power supply is designed for stationary installation, with mains power applied via a detachable power supply cord or via direct wiring to the source power terminal block. 3. This power supply is considered a Class 1 (earthed) product, and as such depends upon proper con- nection to protective earth for safety from electric shock. (EN61 010-1 Cl. 6.5.4) 4. This power supply is intended for use as part of equipment meant for test, measurement and labora- tory use, and is designed to operate from single phase, three wire power systems. This equipment must be installed within a suitably wired equipment rack, utilizing a three wire (grounded) mains con- nection. See wiring section of this manual for complete electrical wiring instructions. (EN61010-1 Cl. 6.5.4 and Cl.6.10.1) 5. This power supply has secondary output circuits that are considered hazardous, and which exceed 240 VA at a potential of 2V or more. 6. The output wiring terminals of this power supply has not been evaluated for field wiring and, therefore, must be properly configured by the end product manufacturer prior to use. 7. This power supply employs a supplementary circuit protector in the form of a circuit breaker mounted on the front panel. This circuit breaker protects the power supply itself from damage in the event of a fault condition. For complete circuit protection of the end product, as well as the building wiring, it is required that a primary circuit protection device be fitted to the branch circuit wiring. (EN61 01 0-1 Cl. 9.6.2) 8. Hazardous voltages are present within this power supply during normal operation. All operator adjust- ments to the prcilduct are made via externally accessible switches, controls and signal lines as speci- fied within the product operating instructions. There are no user or operator serviceable parts within the product enclosure. Refer all servicing to qualified and trained Kepco service technicians.

Installation, Operation and Service Precautions This product is designed for use in accordance with EN 61010-1 and UL 3101 for Installation Category 2, Pollution Degree 2. Hazardous voltages are present within this product during normal operation. The product should never be operated with the cover removed unless equivalent protection of the operator from accidental contact with hazardous internal voltages is provided: 2. Grounding There are no operator seJViceable parts or adjustments within the product enclosure. Refer all seJVicing to trained seJVice technician. Source power must be removed from the product prior to performing any seJVicing. This product is factory-wired for the nominal a-c mains voltage indicated on the rat- ing nameplate located adjacent to the source power connection on the products rear panel. To reconfigure the product input for other nominal mains voltages as listed herein, the product must be modified by a trained seJVice technician. This product is a Class 1 device which utilizes protective earthing to ensure operator safety. The PROTECTIVE EARTHING CONDUCTOR TERMINAL must be properly con- nected prior to application of source power to the product (see instructions on instal- lation herein) in order to ensure safety from electric shock. PROTECTIVE EARTHING CONDUCTOR TERMINAL-This symbol indicates the point on the product to which the protective earthing conductor must be attached. EARTH (GROUND) TERMINAL - This symbol is used to indicate a point which is connected to the PROTECTIVE EARTHING TERMINAL. The component installer/ assembler must ensure that this point is connected to the PROTECTIVE EARTH- ING TERMINAL. CHASSIS TERMINAL -This symbol indicates frame (chassis) connection, which is supplied as a point of convenience for performance purposes (see instructions on grounding herein). This is not to be confused with the protective earthing point, and may not be used in place of it. 3. Electric Shock Hazards This product outputs hazardous voltage and energy levels as a function of normal operation. Operators must be trained in its use and exercise caution as well as common sense during use to prevent accidental shock. This symbol appears adjacent to any external terminals at which hazardous voltage levels as high as SOOV d-e may exist in the course of normal or single fault condi- tions. This symbol appears adjacent to any external terminals at which hazardous voltage levels in excess of SOOV d-e may exist in the course of normal or single fault condi- tions. 228-1352 SAFETY-(COVER REMOVAL) 062399 C/(0 BLANK) TABLE OF CONTENTS PARAGRAPH PAGE SECTION I -INSTRUCTION 1-1 Scope of Manual . . . 1-1 1-3 General Description. . . 1-1 1-9 Specifications, Electrical. . . . . 1-2 1 -10 Miscellaneous Featrues . 1-5/1-6 1-11 Mechanical Specifications . 1-5/1-6 1-12 Accessories . 1-5/1-6 2-1 2-3 24 2-6 2-8 2-10 2-13 2-14 3-1 3-3 3-6 3-12 SECTION II-INSTALLATION Unpacking and Inspection . .2-1 Terminations . 2-1 A-C Input Reljurrcrnents . .2-4 Cooling . . . .2-4 Preliminary Check-Out.
