Safety Precaution: Notes

WARNING: Since electric vehicles contain high voltage batteries, mishandling the high voltage system or vehicle may lead to a serious accident, including electric shock and electric leakage.

WARNING:

Be sure to shut off the high voltage by removing the safety plug before inspecting or repairing the high voltage system (Refer to "HIGH VOLTAGE SHUT-OFF PROCEDURES ").
A responsible worker should keep removed safety plugs to prevent it from being connected by mistake.
Keep away from any metal objects (watch, ring etc.) while working on the high voltage system, as they may cause serious accidents like electric shock.
Before beginning to work on the high voltage system, workers should wear personal protective equipment to prevent safety accidents (Refer to "PERSONAL PROTECTIVE EQUIPMENT ").
At any time, do not allow workers not wearing personal protective equipment to touch the high voltage system. High voltage components should be covered with an insulation sheet to prevent safety accidents.
Do not take over 70°C (158°F)/30min or 80°C (176°F)/20min when painting because exposing a high voltage battery to intense heat may cause deterioration.
Use insulation tools when working on the high voltage system.
Place removed high voltage components on an insulation mat.
Check that voltage between the high voltage terminals is below 30V after removing the safety plug.

Information

All the high voltage wiring and connectors are in orange.
A caution label for high voltage is attached to the high voltage components
High voltage components: High Voltage Battery, Power Relay Assembly (PRA), Quick Charge Relay Assembly (QRA), Motor, Power Cable, BMS ECU, Inverter, LDC, On-Board Charger (OBC), Main Relay, Pre-charge Relay, Pre-charge resistor, Battery Current Sensor, Safety Plug, Main Fuse, Battery Temperature Sensor, Bus Bar, Charge Port, A/C Compressor, Electric Power Control Unit (EPCU), High Voltage Heater, High Voltage Heater Relay etc.

CAUTION:

Inform of possible danger of high voltage by placing a "high voltage caution" sign on the vehicle as in the image below.
