Safety Precaution: Notes
WARNING:
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.
WARNING:
- 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.
Information
- 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.
WARNING:
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.

CAUTION:
Inform of danger of high voltage by putting the "high voltage caution" on the vehicle as image below.

WARNING:
Be sure to follow instructions below when repairing the high voltage cable.
- Check the voltage of the high voltage connector, terminal or busbar before repairing.
Below 30V: High voltage circuit properly shut
More than 30V: High voltage circuit faulty
- Be careful not to short circuit between positive (+) and negative (-) terminals.
- Insulate the high voltage connector or terminal with an insulation tape after disconnecting.
- Tighten the high voltage terminal with the specified torque.
CAUTION:
The high voltage battery must be always handled horizontally during repairing or storage. Otherwise, there may be decline in battery performance or its life may be shortened.
CAUTION:
Exposing the high voltage battery to intense heat may cause deterioration.
Do not bake over 70°C (158°F)/30 min or 80°C (176°F)/20 min when painting.
Do not bake over 70°C (158°F)/30 min or 80°C (176°F)/20 min when painting.
