Electrical connection
Supply Voltage
Warning: Risk of death by electric shock! Components have voltage applied. Contact with current
conducting parts results in an electric shock, burns or death. When working with the electrical
system, the following procedure must be followed:
•
Disconnect device from voltage.
•
Secure the device from being turned back on.
•
Ensure that no voltage is applied.
•
Earth and short-circuit the device.
•
Cover neighboring components that are under voltage and secure the danger area.
Consider the following when connecting to the power supply:
•
Abide by the national/local regulations.
•
Ensure a clockwise rotating field for a three-phase connection.
Safeguarding and personal protection
Warning: Danger to life by electric shock. Residual current circuit breakers (type B) sensitive to
universal currents may be installed instead of residual current circuit breakers (type A) sensitive to
pulse currents. In accordance with IEC 61851 standard, all charging stations are fitted with residual
current device (RCD).
Warning: Fire hazard due to device overload.
Fire hazard due to device overload in case of wrong design of the on-site circuit breaker. The
normal current of the selected circuit breaker must not exceed the specifications on the nameplate .
Warning: Risk of injury or death when incorrectly installed. Risk of injury if installation is done by
unqualified personnel.
