7. WARNING Extreme caution is required when performing maintenance Be constantly aware that the UPS system contains high DC as well as AC voltages With input power off and the battery disconnected high voltage at filter capacitors and power circuits should be discharged within 30 seconds However if a power circuit failure has occurred assume that high voltage still exists after shutdown Check with a voltmeter before making contact AC voltage will remain on the bypass and output contactors and the static bypass switch unless associated external circuit breakers are opened Check for voltage with both AC and DC voltmeters before making contact When the UPS system is under power both the operator and any test equipment must be isolated from direct contact with earth ground and the UPS chassis frame by using rubber mats Some components within the cabinets are not connected to chassis ground Any contact between floating circuits and the chassis is a lethal shock hazard Use differential oscilloscopes when measuring a floating circuit The differential input should have at least 800 vrms common mode input rating and a common mode rejection ratio of at least 80db Exercise caution that the test instrument exterior does not make contact either physically or electrically with earth ground In case of fire involving electrical equipment use only carbon dioxide fire extinguishers or others approved for use in fighting electrical fires 37 L
