The height of the foundation is determined by the topography and natural environment of the site. Depending
on rainfall and drainage a height between 6 inches (150mm) and 12 inches (300mm) above the ground is
recommended. For frost-proofing, the foundation should extend approximately 31.5 inches (800mm) under the
ground.
The recommended size for foundation conduit is 5.9 inches (150mm).
NOTE:
•
The unit must be mounted on a level, solid, flat concrete slab.
•
Some types of slabs require the use of expansion bolts, which may require drilling. Select suitable
mounting hardware.
•
The laying of power cables shall be in accordance with NEC guidelines and local electrical codes.
•
Cable design shall be selected according to the number of chargers and the type, power, voltage and
current level of the equipment installed.
•
Laid cables must be properly enclosed in conduit adhering to all safety requirements.
•
When the cable is buried directly, the buried depth should not be less than 32 inches (800mm) to prevent
freezing.
•
Power cable specifications should be selected according to NEC guidelines and shall consider
environmental and fire code requirements.
