ChargePoint Express 280 - Page 17

l
Contains #4 rebar or larger, top and bottom, 305 mm (12 in) on center
l
Concrete 2500 PSI minimum
The above pad specifications are designed to meet these conditions:
l
170 mph wind speed
l
Wind Risk Category I
l
Wind Exposure D
l
Seismic Importance Factor 1.0
l
Hayward Fault with mapped spectral response accelerations Ss=2.45 S1=1.019
l
Seismic Design Category E
l
Foundation of Sandy Soil with allowable stress = 1500 psf, Cd = 1.33
In some extreme conditions, a larger pad would be required. For sites with less stringent seismic, soil, or
wind conditions, a smaller pad might be possible.
If the existing pad does not meet the specifications above, it must be inspected and approved by a
structural engineer for the station's dimensions and weight. If needed, give these structural design
specifications to the structural engineer for verification:
Product Weight 340 kg (750 lbs)
Product Height from Ground 2.413 m (7.917 ft)
Product Width 0.42 m (1.378 ft)
Product Frontal Area Height * Width
CG Height 1.12 m (3.66 ft)
Number of Anchor Bolts 4
Bolt Pattern See dimensions below.
Anchor Bolt Size M16 (5/8 in)
Anchor Bolt Embedment 229 mm (9 in)
Express 280 stations use the DC Universal Concrete Mounting Template (CMT), which also fits other DC
fast charging stations such as the Express 250. This CMT is embedded in a newly poured concrete pad to
position both the anchor bolts and the conduit stub-ups detailed above. For conduit and anchor bolt
configurations and assembly instructions, see DC Universal Concrete Mounting Template Guide.
