There is overcurrent protection detection assembly inside the charger. However, a short circuit protection
device must be installed at the front end of the charger power supply incoming line, for example, an air switch
must be installed at the front end of the charger power supply incoming line.
Do not use the charger if short circuit protection device is not installed.
The rated current of short circuit protection device is about 1.2 times of the maximum current of the
charger.
If the charger is running at full load, it is recommended that the rated current of short circuit protection
device shall be 40A.
Class B or Class C air switch must be installed at the front end of the charger power supply incoming
line. If you have any questions about the selection of air switch, you can contact the manufacturer directly.
6.4 Install residual current protection device
According to IEC61851-1 standard, the charger must include electric leakage protection function. When
AC electric leakage (AC electric leakage signal ≥ 30mA) or DC electric leakage (DC leakage signal ≥ 6 mA)
occurs during charging, power supply for charging will be disconnected.
Type B electric leakage detection device of the charger is built in the charger.
The selection and installation of electric leakage detection device must be carried out by
professionals.
6.5 Overvoltage protection
The overvoltage level of the charger meets Class III overvoltage protection.
6.6 Power incoming line Installation
The cross-sectional area of the power supply incoming line connected to the charger must be in the range of
6-10 mm
2
.
Power incoming line must be selected by professional installers, please refer to national safety
regulations and the latest electrical installation technology!
6.7 Power supply system
Both of single-phase or three-phase chargers support the following power supply systems:
