Concrete Foundations
DKP210 can be mounted on a new or an existing concrete block. The
pole mast is fixed to the concrete block with foundation bolts.
NOTE The minimum weight of the main mast block is 400 kg (882 lb.).
When constructing a new concrete block, fasten the foundation bolt
assembly simultaneously with the concrete pour. If there is an existing
concrete foundation, you have to drill the holes for the foundation bolts.
In both cases, use the delivered orientation plate for the correct placing of
the foundation bolts. For the protection of the cables, it is recommended
that you install a cable conduit, which has a minimum diameter of 70 mm
(2.76 in.). See Figure 6 below.
