INSTALLATION
FOUNDATION REQUIREMENTS
A dedicated foundation is not necessary when the equipment is installed indoors or in higher and drier sites,
but the ground level plan error per square meter must not exceed ±1.5mm, and the ground strength level of
the installation position must not be less than C30. When the equipment is installed outdoors and in low-lying,
damp or potentially humid environments, a cement or slot steel base must be installed. The cement base must
be 200mm above the ground (the recommended height below the ground is not less than 500mm). The mounting
surface requires four pre-buried M6 stainless steel bolts, bolt thread exposed to the ground 30±3mm.
The cable wire enters through the bottom of the charger through an inlet hole.
On the ground where the charger is to be installed, dig a hole not smaller than the base dimensions indicated
in the gure below.
Make sure that the cable is accessible from the pre-buried pipe.
Pour the concrete into the concrete foundation shown in the gure below.
It is recommended that the base of the charger be at least 200mm above the ground, effectively reducing the
risk of ooding.
Reserve a cable length of 1m above the base for internal wiring.
Fill the inside and outside of the base with sand and stone. The inlet holes may need to be blocked to prevent
small animals such as rats from entering the equipment.
