XII.3. DS200M
1- A location that complies with the requirements stated in the preparation step is plotted.
2- By making use of the mounting template that comes with the DS200M rack, the locations
for the wall mount bars that are to be used for hanging the racks on the wall are marked
carefully. The holes of the screws should be approximately 130 cm. above the floor. It is
essential to check whether the height of both right and left holes are the same, in order to
make sure the exchange is parallel to the floor.
3- The anchor plugs are driven into the holes, correctness of whose locations has already
been verified, and then the wall mount bars are screwed into the anchor plugs. One must
keep in mind that the right and the left sides of the wall mount bars differ. The screws
should be tightened to penetrate into the wall such deeply that 7-mm segments of their
heads remain outside the wall, i.e., they should not penetrate entirely into the wall.
4- The exchange is held against the wall, so that larger edges of the wall mount bar holes
on the back of the exchange (pear-shaped) corresponds to the screw heads, then the
exchange is pushed towards the wall to allow the screws to carry it. After one makes sure
that the heads of both screws have been inserted into the holes, the exchange is lowered
cautiously. The exchange is supposed to halt at its final position 10 mm. below. If it is still
not fixed even though it has been lowered for about two centimeters, then that indicates
the screws do not carry it. In that case, another attempt to hang the exchange on the
screws should be repeated. Before the exchange is released, it should be shaken gently
to the right and left to check whether it is actually carried by the screws, in order to make
sure the exchange has thoroughly been fixed on the wall.
