1.2. Tools and materials
1.2.1. Tools
• A set of Torx, Phillips, and Flathead screwdrivers with insulated handles, set of hex keys
• Torque limited drill or cordless screwdriver, drill bits for masonry (8 mm)
• Hammer drill and bits
• Electrician kit, including pliers, strippers, ferrule and RJ-45/11 crimping tools
1.2.2. Materials
• Conductors (insulated single-core or stranded), conduit, cable tie-downs, cable clamps
• Signal cables (UTP5 cable)
• Connectors (RJ-45/11) and ferrules
• Insulation materials
• Wall anchors for mounting the charger body
1.2.3. Site survey and selection
The charger can draw up to 32A per phase at 230VAC and shall be installed on a dedicated
circuit(s). The entire building electrical installation must be adequately sized to accept this load
under peak loading conditions. Ensure that all elements of the electrical installation, from the
utility connection, through to the dedicated charger circuit are adequate for the rated
power.
Ensure that the distribution panel has a position for 1/3 dedicated circuit breakers (CBs).
Although the charger has overcurrent protection, each phase must be protected with an
individual CB. Details are provided in the following sections regarding its rating and
possibilities to derate.
The charger is designed for indoor and outdoor installation. To ensure a long service life, select
a location that is not exposed to harsh elements, such as direct sunlight and rainfall, has proper
ventilation and normal humidity.
Consideration about connectivity must also be made. For example, if the charger is to be
connected online via Wi-Fi, select a site within range of the wireless network to ensure a steady
connection. Alternatively, select a site with easy access to a wired network connection or mobile
network coverage. Consider that CT clamps, which are installed at the main distribution panel,
need a wired connection to the charger. If a MID meter is to be installed, allocate space which is
compliant with the manufacturer's requirements.
ELECTRICAL CIRCUIT PROTECTION
A type 2 surge protection device should be installed according to the guidance on requirements
in BS7671:2018 section 443.
All installations must comply with current wiring regulations (18
th
Edition Wiring Regulations
BS767) and be carried out by a qualified electrician.
