USR/CNR indicates investigation to the U.S. and Canadian (Bi-National) Standard for Safety of Information Technology Equipment – Safety – Part 1: General Requirements, CSA C22.2 No. 60950-1-03 * UL 60950-1, First Edition. The equipment is: power system. For building in, Class I (earthed), for use on a TN File E135803 Vol. 1 Sec. 44 and Report Page 2 Issued: Revised: 1999-09-01 2006-01-04 Conditions of Acceptability - When installed in the end-use equipment, the following are among the considerations to be made: 1. This component has been judged on the basis of the required spacings in the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, CSA C22.2 No. 60950-1-03 * UL 60950-1, First Edition, which would cover the component itself if submitted for unrestricted listing. 2. All secondary output circuits are SELV and are not hazardous energy levels. 3. The terminals and connectors have not been evaluated for field wiring. 4. The power supply shall be properly bonded to the main protective earthing termination in the end product as this unit was investigated for Class I construction as defined in UL 60950-1. An additional evaluation shall be made if the power supply is intended for use in other than Class I equipment. 5. Bonding terminals provided on this equipment have not been evaluated as protective earthing terminals. 6. Magnetic device transformer T3 employs an OBJY2 electrical insulation system designated Class F. Inductor T2 employs bobbin material rated 150°C in the thickness used. 7. The equipment has been evaluated for use in a Pollution Degree 2 environment. 8. The component shall be installed in compliance with the enclosure, mounting, spacing, casualty markings and segregation requirements of the end-use application. 9. This power supply was evaluated for use in a 50°C ambient. An additional evaluation should be made if the power supply is intended to be used in an elevated ambient. File E135803 Vol. 1 Sec. 44 and Report Page 3 Issued: Revised: 1999-09-01 2006-01-04 CONSTRUCTION DETAILS: See Section General for additional details. Operating/Instruction/Safety Manual - Provided with each unit. ILL. 2. See Printed Wiring Board - See Section General for details. General appearance of trace layout same as in ILL. 1. Board rated 130°C. Model Differences - All models are the same, except for output ratings and differences in secondary, low voltage circuitry. Suffix L indicates chassis is provided. Suffix LC indicates a cover and chassis is provided. Models followed by the suffix –XXX represents value added configurations that have no impact on safety. Model SP1683 is identical to GLC110-12 except that it uses an alternate PWB that provides an alternate pinout on the secondary output connector, and the value for the Line-to-Ground capacitors C3 and C4 is reduced to 1500 pF.
