Hybrid Control System
Safety Precaution
Precautions to take before servicing high voltage system
• Since hybrid vehicles contain a high voltage battery, if the high voltage system or vehicles are handled incorrectly, this might lead to
a serious accidents like electric shock and electric leakage.
• Be sure to shut off the high voltage by removing the safety plug before performing inspection or repairing the high voltage system.
(Refer to "High Voltage Shut-off Procedures")
• The responsible worker keeps the removed safety plug to prevent the plug from being connected by mistake.
• Do not keep any metal objects (watch, ring etc.) while working on the high voltage system, which it can cause serious accidents like
electric shock.
• Before beginning work on the high voltage system, the worker should wear personal protective equipment to prevent safety
accidents.
(Refer to "Personal Protective Equipment")
• Never allow workers who are not wear personal protective equipment to touch the high voltage system. High voltage components
should be covered with an insulation sheet to prevent safety accidents.
• Use insulation tools when working on the high voltage system.
• Put the removed high voltage components on the insulation mat.
• All the high voltage wiring and connectors are orange.
• A caution label for high voltage is attached to the high voltage components.
• High voltage components :
High Voltage Battery Pack Assembly, Power Relay Assembly (PRA), BMS ECU, Hybrid Power Control Unit (HPCU), Hybrid Drive
Motor, HSG, Electric A/C Compressor, Low DC/DC Converter (LDC), Power Cable, Electric Compressor etc.
• Inform of danger of high voltage by putting the "high voltage caution" on the vehicle as image below.
