Electrical protection devices
The SICHARGE UC Dispenser is equipped with multiple electrical protection devices.
NOTE
No EMERGENCY OFF button on the SICHARGE UC Dispenser
The EMERGENCY OFF button is installed directly on the connected SICHARGE UC charging
station.
On the outside of the SICHARGE UC Dispenser, attach a visible map with the location of the
connected SICHARGE UC charging station. All persons in this area must be instructed on how
to act in an emergency.
Resetting alarm states
Alarm states may only be reset by qualified electricians.
Overvoltage protection
The overvoltage protection is provided by an upstream SICHARGE UC charging station.
The SICHARGE UC charging station offers comprehensive protection against overvoltages
from the distribution network. Varistors with short response times protect each line
conductor of the power cable against overvoltages. In addition, the control system of the
charging station constantly monitors the mains voltage. If the mains voltage exceeds or falls
below the permissible limits, the charging station interrupts the charging process in progress
or does not start the charging process.
Overload protection
The charging controller at the charging station constantly monitors the input current and the
output current. In addition to the main contactor, AC and DC contactors, there are further DC
contactors at the dispenser. If a measured current value exceeds the default limit values, the
controller stops the charging process and opens the contactors. The open contactors
electrically separate the charging module and the vehicle. The charging current ceases to
flow between the SICHARGE UC Dispenser and the vehicle. A fuse at the input protects the
SICHARGE UC Dispenser from overcurrents.
