Installation Preparations - Huawei SCharger-7KS-S0 User Manual

Installation Preparations

Before the installation, ensure that:
The charger power is within the allowed load range of the residence.
Cables and RCBOs meet the installation and usage requirements.
If the AC input power cable exposed to the outdoor environment is 3 m or longer, consult the local installer. You are advised
to install a surge protective device (SPD) at the upstream of the charger's RCBO. The SPD specifications should meet the
following requirements: Uc = 385 V AC, In ≥ 10 kA, and Up ≤ 2 kV. The cable between the SPD and charger must be at
least 3 m.
A network cable that is long enough is prepared if the charger is connected to a wired network.
The installation area should be covered by a wireless network if the charger is connected to the network through WiFi.
If the PV power preferred mode and dynamic charging power mode are used, you need to configure an electricity meter. Scan the
QR code in "About This Manual" and see detailed information about the meter in "Meter Description."
