Theswitch requires no routine maintenance; however, theswitch should be inspected on a regular basis to check forphysical damage and to verify operation.Frequency of inspectionBecause these switches are applied under widely varyingoperation and climatic conditions, maintenance intervalsare best determined by the user based upon actualoperating experience.WARNINGHazardous voltage The switchgear (apparatus andcontrol) and high-voltage transformer must be in a testcage or similar protected area to prevent accidentalcontact with the high-voltage partsSolidly ground all equipment Failure to comply canresult in death, severe personal injury, and equipmentdamage T221 5CAUTIONRadiation At voltages up to the specified test voltages,the radiation emitted by the vacuum interrupter isnegligible However, above these voltages, radiationinjurious to personnel can be emitted See ServiceInformation S280-90-1, Vacuum Interrupter WithstandTest Voltage Ratings Information, for further informationG109 2
