Prepare for Installation
3
Before beginning work, check that the site meets these civil and mechanical requirements outlined
below, as illustrated in the following image. Measurements are in mm (in):
•
The concrete pad is ready and the concrete is fully cured and level.
•
The concrete pad either has a site drawing approved by a structural engineer for this specific
site, OR conforms to these specifications:
•
At least 305 mm (12 in) deep (or deep enough to be 305 mm (12 in) below the frost line)
•
At least 1296 mm (51 in) on each side
•
Walls, fences, or slopes do not prevent water from draining from the pad.
•
The concrete mounting template (CMT) is installed in the concrete pad, 50.8 mm (2 in) below
the concrete surface, with anchor bolts in place in the CMT.
•
The AC conduit (max 50.8 mm/ 2 in trade size) and shunt trip conduit (max 19.1 mm/ ¾ in size)
are positioned correctly in the CMT and cut down to 76.2 mm (3 in) above grade.
•
Paired only: The DC conduit (max 76.2 mm/ 3 in trade size) and Ethernet conduit (max 19.1 mm/
¾ in size) are positioned correctly in the CMT and cut down to 76.2 mm (3 in) above grade.
•
The service clearance of open space (not necessarily at system grade) extends a minimum of
610 mm (24 in) beyond the station in front, 1276 mm (50 in) total front to back, 2156 mm
(84.8 in) side to side centered on the station, and 305 mm (12 in) above the station (image
callout a).
•
The front of the station has 352 mm (14 in) of space at grade from the front right anchor,
extending 1700 mm (67 in) to the left, without any permanent obstructions (bollards, wheel
stops, etc) (b).
•
Charging station sites are positioned so that each station is centered on a parking space (unless
curbside), with the front of the station facing the vehicle. (This maximizes cable reach.)
•
The charging station is at least 305 mm (12 in) from any wall as its rear clearance. Stations
positioned back to back are no closer than 610 mm (24 in) shared clearance.
If the site does not meet these basic requirements, contact ChargePoint before continuing.
