File E135803 Vol. 2 Sec. 8 and Report Page 2 Issued: Revised: 2000-01-19 2005-12-13 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 for building in, Class I (earthed), for use on a TN power system. 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 T2 employs an OBJY2 electrical insulation system designated Class F. Inductor T1 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. 10. All power supplies, except Models GLC50-3.3 and GLC50-5 comply with the Limited Power Source requirement in Clause 2.5 of UL 60950-1.
