MECHANICAL INSTALLATION
CONCRETE PAD
A concrete pad constructed from 3,000-4,000 psi-concrete should be used. Electrical conduit for AC power
should be positioned such that it exits the concrete pad at the Main AC power line opening (see: Figure 2).
Alternative Anchor Installation
– 4 places
Use Hilti 1/2” KB-TZ SS 304 anchors (see: Appendix A Hilti Technical Information). Ensure that the
concrete has cured in accordance with the concrete and Hilti requirements. Position of the anchors shall
be in accordance to Figure 3 and installed per Hilti instructions. A ground rod will be needed and
installed.
PREPARATION
Ground Rod Connection: Use acorn
clamps to two #2 bare copper wire from
the ground rod to the first rear anchor bolt,
as shown on the diagram.
SIDE ELEVATION
▪
The concrete foundation needs to be sized
in accordance with local jurisdiction code(s). The
foundation referenced is 2 ft. deep and contains
rebar, as noted above.
▪
The foundation for the charger should have
a maximum height of 6 in. above finished grade.
‘Finished grade’ is defined as the location where the
user operating the charger will stand. Foundations
that extend higher than 6 in. above finished grade
will cause the charger controls to be above
ADA-compliant maximum standards and could result
in a failed inspection, possibly requiring the foundation
be lowered in order to meet ADA guidelines.
