may be government regulations, local regulations, or site-specific rules that govern the operation, service, and maintenance of hazardous voltage components and machines. Comply with applicable rules and regulations for the work place.There may be government regulations, local regulations, or site-specific rules that govern the methods of isolation, placement of warning tags, and the prevention of re-energizing electrical components and machines. Comply with all applicable rules and regulations for the work place.Appropriate hazardous voltage protective equipment should be worn as defined by local rules and regulationsOnly qualified service personnel should perform service on hazardous voltage systems.DO NOT remove covers, or open enclosures, that will expose energized hazardous voltage electrical components.DO NOT perform service or maintenance on energized hazardous voltage electrical components.Hazardous voltage can cause electrocution resulting in personal injury or death.Hazardous voltage components and connections must be properly maintained.Refer to Operation and Maintenance Manual, Maintenance Section for additional information.Residual energy can remain in hazardous voltage components even after operation has stopped. Always assume that a hazardous level of voltage could be present.Before performing any type of service, repair, or maintenance on hazardous voltage electrical components, perform the following:
Disconnect the electrical power source
Isolate electrical components
Discharge residual energy
Check components for voltage using electrical measuring tools.Note: Use electrical measuring tools that have the capacity to measure the hazardous voltage components being checked. The level of voltage present must be confirmed to be below 50 VDC before any exposure to the hazardous voltage components can take place.Read and understand the instructions and warnings found in Operation and Maintenance Manual, "Electrical Shutdown and Voltage Discharge" , to properly shutdown the electrical system and discharge hazardous voltage electrical components.
