15 q cut the thread in the holes for the enclosure feet in one of the alumi- num profiles, us- ing the supplied special m4 screw as a tap. Q mount the feet on the aluminum profile, using two m4 hexagonal al- len screws. Use the supplied allen wrench. It is advisable to stick the protection adhe- siv...
Page 16
16 q position the main pcb in the aluminum profile that is prepared with the feet. Q mark the center position of the three fixation holes on the aluminum. A refer- ence indication is also on the pcb edge. Q remove the pcb and use a knife or a screwdriver to scratch the paint from the aluminum fixati...

17 q using an ohmmeter, measure between the edge of the aluminum profile and the back spacer, if there is a good electric contact (less then 10 ohm). If not, repeat the above step to remove the paint under the spacer. Q slide two m3 nuts and two hexagonal bolts into the pro- file, the nuts will be u...
