IBM 6500-V20 Maintenance Manual - Page 21

Preparation Safety Inspection IMPORTANT Safety devices to protect customers, operators, and service personnel from injury are installed in all IBM printers. Use this inspection guide as an aid in identifying possible unsafe conditions in an Infoprint* 6500 printer. Do the inspection steps outlined in this section before the normal inspection for Maintenance Agreement Qualification, or any time you are instructed to make a safety inspection. If you find any unsafe conditions, determine the severity of the hazard and whether or not you can continue the inspection without first correcting the problem. The correction of any unsafe condition is the customer's responsibility. Preparation You must have completed the "CE Basic Electricity" training course (self-study course number BOPS08XS or current level) to do this Safety Inspection. Have the following items available: • Electrical Safety for IBM Customer Engineers, Order No. S229-8124. • A Fluke** meter (P/N 8496278) or similar device for measuring electrical resistance and voltage. • An ECOS** Electrical Safety Tester (P/N 6339695) in the United States or a similar safety tester in other countries. For each safety check on the following pages, do the steps in the order presented. Do not omit any steps. Prepare The Printer For Inspection To prepare the printer for a safety inspection, read the safety notices below, then do all the steps that follow. DANGER Hazardous voltages are present in the printer with the power cord connected to the power source. Switch off printer power and unplug the printer power cord before proceeding. Do not connect or disconnect any communication port, teleport, attachment connector, or power cord during an electrical storm.
