Safety instructions
To ensure the safety of persons and property during maintenance and servicing of the
charging station, observe the following safety instructions.
WARNING
Qualified personnel
Only qualified and trained persons may work on SICHARGE D. Only qualified and instructed
electricians may work on the SICHARGE D.
WARNING
Electric shock from live parts
Electrical systems have live parts during operation. If the system has not been disconnected
from the power supply before maintenance work is performed inside the station, death,
serious injury or damage to property may occur.
•
Only perform maintenance and service work inside the station when the charging station
is disconnected from the power supply.
•
Observe the five safety rules for electrical work (Page 13).
WARNING
Electrical shock due to residual charges in capacitors
After switching off the power supply to the charging station, the capacitors begin to
discharge. Live parts remain under dangerous electrical voltage for up to 10 minutes during
discharging. Touching the live parts can lead to death or serious injury.
•
Wait 10 minutes after switching off the power supply.
•
Ensure that the charging station is not live.
•
Only then should you start work on the charging station.
WARNING
Hot surfaces
When opening the front or back door, you can easily come into contact with hot surfaces.
This applies, for example, to the area of the AC/DC converters or the copper bars. Before
starting work, wait at least 10 minutes after switching off the charging station until all hot
surfaces have cooled down.
