Preventive measures against electrical hazards

CAUTION

Risk of injury from arcing during a high-energy discharge (between two conductive metals).
Minor injuries.
- Make sure control cabinets are kept closed unless electrical components are de-energized.
- Disconnect any energy storage units such as accumulators from the electronics. Observe the measures for shutdown of the products used.
- Switch off other voltage sources.
- Before switching on the product, make sure that the protective cover is in place over the connections.
- Ensure that the product is insulated as far as possible and that no conductive foreign bodies can penetrate.

WARNING

Electric shock when connecting or disconnecting energized power connections.
Severe or fatal injuries.
- Disconnect all supply voltages.
- Make sure that the devices of the system are de-energized.
- Never connect or disconnect the power connections while they are energized.
- Never disconnect the power connections if you do not know the actual state of charge of the energy storage unit.
- Discharge the energy storage units to less than 3 V before disconnecting them from the DC link.
