PME Earth Fault Monitoring:
The charger complies with BS7671:2018 (including amendment 1:2020) wiring regulations. For TN-C-S (PME) systems, it features an open protective earthed-neutral (PEN) detection device, potentially eliminating the need for a dedicated earth rod. In case of a fault, charging is stopped, and the car is isolated from the supply.
Self-Monitoring and Recovery:
The charger automatically resets after minor faults such as Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Temperature Protection (OTP), or Over Current Protection (OCP). Internal RCD or PME faults can be configured for manual or automatic resetting.
OCPP 1.6J Full Profiles & Smart Charging Support:
Supports OCPP 1.6J full profiles, including smart charging for managing charging station loads with limited power supply. iCS offers its own OCPP software for comprehensive management.
Usage Features
Installation Overview:
The installation process involves seven steps:
- Check the box contents.
- Wall mounting and wiring.
- Install the charger.
- Verify the installation.
- Quick Setup (Server).
- Quick Setup (Network).
- Further configuration.
Safety Instructions:
- Warnings: Do not install or use near flammable, explosive, harsh, or combustible materials. Turn off input power at the circuit breaker before installation or maintenance. Stop use if defective or damaged. Do not attempt to open, disassemble, repair, tamper with, or modify the charger. Do not touch the charger socket with metallic objects or put fingers into it. Do not use if the EV charging cable or enclosure is frayed, broken, or damaged.
- Cautions: Installation must be performed by a qualified technician, adhering to local building codes and safety standards. Incorrect installation may damage the vehicle's battery or the charger, voiding the warranty. Operate within -30°C to +50°C. Ensure the EV charging cable is positioned correctly. Do not use cleaning solvents on components.
