Machine Interface Receptacle with Voltage Divider Board
3. Install the voltage divider PCB as follows. Refer to
a. Put the voltage divider PCB cable
CPC.
b. If an RS-485 serial interface PCB
of the RS-485 PCB.
c. Push the voltage divider PCB
the plastic tabs
d. Put the voltage divider PCB cable above the fan. Make sure that the routing of the voltage
divider PCB cable is as shown in
4. Install the 2 ground wires as follows. Refer to
a. On the fan side of the plasma power supply, remove the screw from the ground stud
b. From the power PCB side, put the green and yellow ground wire
interface receptacle through the power cord grommet.
c. Put the machine interface receptacle ground wire on the ground stud
ground stud screw at this time.
d. Put the green voltage divider PCB ground wire
the fan. Make sure that the routing of the ground wire is as shown in
e. Put the voltage divider PCB ground wire on the ground stud
f. Install the screw loosely on the ground stud with your fingers.
g. Rotate the ground wire terminals on the stud so that each wire points in a different direction.
Make sure that all of the other ground wires stay connected to the ground stud. Refer to
Figure 2.
h. Tighten the screw to 1.7 N·m (15 in·lb).
5. Install the 2-pin connector cable
a. Put the 2-pin connector cable from the voltage divider PCB through the power switch
grommet and the slot in the middle panel
b. Connect the 2-pin connector to the power PCB at J17
connector and the red wire is at the bottom.
6. Install the 4-pin connector cable
interference, install the cable holders correctly.
a. Put the 4-pin connector cable above the black plastic mounting posts
holders
