C H A P T E R 2 2. System Operation 2.1 Introduction This chapter describes how to operate the 8000 mainframe. Module specific details can be found in the module's manual. 2.2 Installation CAUTION Although ESD protection is designed into the 8000, operation in a static-fee work area is recommended. CAUTION Do not plug-in or unplug a module with the AC power on. 2.2.1 AC Power Considerations The 8000 can be configured to operate at a nominal line voltage of 100, 120, 220, or 240 VAC. Normally, this is done at the factory and need not be changed before operating the instrument. However, be sure that the voltage setting is correct on the power input module and correct fuses are installed per section 5.2 before connecting to an AC source. The 8000 is shipped set for 120 VAC and a caution sticker is placed on the input power connector. CAUTION Do not exceed 250 VAC on the line input. Do not operate with a line voltage that is not within ±10% of the line setting. Too low of an input voltage may cause excessive ripple on the DC supplies. Too high of an input voltage will cause excessive heating. WARNING To avoid electrical shock hazard, connect the instrument to properly earth-grounded, 3-prong receptacles only. Failure to observe this precaution can result in severe injury or death. 7
