2. By referring to the dimension shown in Figure 2-1, mark the central points of the installation holes on the wall. Use
an electric drill (aiguille: Φ8) to dig holes (depth: 45mm) at the marked points. Clean the holes off dust. Put the four
expansion pipes (M6 × 65) into the holes and keep 20mm exposed.
3. As shown in Figure 2-2, use four groups of flat washer Ф6, spring washer Ф6 and nut M6 to fix the power system on
the wall.
4. After the installation, the power system should stand firmly no matter how it is shaken.
5. If rack mounting installation is used, firstly remove the three brackets, turn the bracket with the grounding screw to
make the grounding screw facing forward, and then fasten the bracket to the front of the subrack left side wall,
meanwhile, fix any one of the other two brackets after rotation to the front of the subrack right side wall (the rest
bracket is no need to be fixed). The position of the bracket is shown in Figure 2-2, use the fixing screws to fasten the
subrack power system to the rack through bracket.
