文档介绍：SONATA HYBRID(YF HEV) > 2012 > G HEV > General InformationGeneral Information > General Information > General Safety Information and CautionSafety PrecautionThis hybrid system uses a DC 270V voltage system. Be sure to follow safety instructions below. Failure to follow safety instructions may result in serious injury or electrocution. A caution label for high voltage is attached to the high ponents. The color of the high voltage cables and connectors are orange. Do not touch any of these high ponents, cables, and connectors without proper Personal Protection Equipment (PPE). High ponent: High Voltage Battery Pack Assembly, Power Relay Assembly (PRA), BMS ECU, Hybrid Power Control Unit (HPCU), Hybrid Drive Motor, HSG, Electric A/pressor, Low DC/DC Converter (LDC), Power Cable, pressor, etc. ? For your safety when servicing the hybrid vehicle : - Wear Personal Protection Equipment (Insulation Gloves and Safety Glasses). - Do not carry any metallic object (watch, ring etc.) which can cause short circuit. - Use insulated tools ? Before wearing the protective gear, make sure that they are not torn or broken and free of moisture. Personal Protection Equipment : Insulating Gloves, Safety Glasses Insulating Gloves Safety Glasses Use Mega Ohm Tester when measuring insulation resistance of the high voltage system. Specification : High Impendance Digital Volt / Ohm Meter (DVOM) "Category 3" Leads and Meter rated to 1,000 voltage. Be sure to shut off the high voltage circuit shown in the procedures below before working on any high voltage ponent (Refer to "High Voltage Shutoff Procedure" for more detailed procedures). the ignition switch off and disconnect the auxiliary 12V battery negative (-) cable. 2. Remove the safety plug (Turning the ignition switch ON with the safety plug removed may damage the hybrid control system). 3. Wait for more than 5 minutes so that the capacitor in the high voltage system can be naturally discharged. the rear seat and parti
