Symbols and DescriptionsSafety ProceduresPersonal SafetyWhen installing or maintaining the Power Xpert Solarinverter, there are exposed components with housings orprotrusions at or above utility and photovoltaic voltagepotentials. Extreme care shall be taken to protect againstelectric shock and arc-flash hazards by de-energizing andisolating all sources of connected and stored energyBEFORE attempting to install or perform work on/inside thePower Xpert Solar.Verify all equipment and tools are properly grounded. Standon an insulating pad and make it a habit to use only the righthand when checking components. Always work with anotherperson in case an emergency occurs.Wear appropriate electrical personal protective equipment(PPE), including safety glasses and hearing protectionwhenever working on this equipment and while operatingrotating or moving machinery during installation orperforming maintenance or service.Disconnect all sources of power prior to accessing anyportion of the inverter following OSHA and NFPA-70Eelectric-shock and arc-flash safety procedures.All Danger, Danger of Electric Shock Hazard; Warning!;Caution!; and Notices! alerts must be followed for the properand warranted use of the inverter.Equipment SafetyThe inverter shall be installed in accordance with allapplicable codes and regulations. Consult the latest editionof NFPA 70: National Electrical Code®. The installer andoperator shall comply with Code, building, fire marshal, andseismic standards and with NFPA 70E. Utility interconnectapproval is required before installation and operation of thismedium voltage grid-tie photovoltaic inverter.Canadian installations shall follow the NEC 690 andapplicable Canadian Standards Association (CSA), CanadianElectrical Code (CE Code), and the National Building Code ofCanada (NBC). Consult all local and utility regulations for solarphotovoltaic.Non-Code compliant installations will adversely affect thesafe usage and serviceability of the inverter, includingapplicable balance-of-system products, including thephotovoltaic modules. Use only modules specific forgrounded PV systems.The inverter is designed and certified to meet the NEC,OSHA, and NFPA-70E standards and installation methods.These shall take precedence over non-USA centricregulations.Lock Out Tag Out (LOTO)When installing or maintaining the inverter, Lock Out and TagOut (LOTO) all Photovoltaic and Grid (utility) disconnectsbefore working on the equipment.A LOTO policy must be in place when working on theinverter and solar site.- or “-”-- or “+”Symbol DescriptionDirect currentAlternating current- sinusoidal waveform -Phase symbol for ACelectricityUsed to identify field-wiringEquipment GroundingConductor (EGC)Used for identifying pointswithin equipment that areintended to be bounded toearth ground (e.g., GET).ONOFFNegative PVPositive PVØ
