4.2.2. Workflow with pre-fabricated concrete foundation
WARNING
Make sure that personnel cannot be crushed or become trapped while
moving the foundation. Be aware that the weight of the concrete
foundation is about 2866 lb.
CAUTION
Before you lower the foundation, remove sharp edges of the cable
holes (B) in the foundation to protect the cables.
1. Make a hole in the ground with at least a minimum depth of 34.84 Inch, shown in the figure
above.
2. Fill the hole with (minimum) 7.87 Inch lean concrete (C), see figure above.
3. Make sure that the conduits are routed to one of the indicated positions (B). The conduits
must come out of the foundation with a length of about 9.84 Inch.
4. Make sure that the AC power cable is routed to one of the indicated positions (B).
5. Lower the foundation (A) into the hole.
6. Make sure that the front top surface of the foundation is at least 0.59 Inch above ground
level (see figure above).
7. Make sure that the top surface of the foundation is leveled.
8. Route the conduits through one of the eight holes (B).
NOTICE
Make sure that the end of the cable conduits are 11.81 to 19.69 Inch
above the top of the foundation.
9. The conduits must be installed with a curve inside the foundation in order to prevent water
from entering the conduits, and seal the space between the conduits and all open holes.
10. Route the AC power cable through one of the eight holes (B). Make sure that a cable
length of 39.37 Inch is available above the surface of the foundation for internal routing in
the cabinet.
