Powermax65/85/105/125, Powermax65/85/105 SYNC Field Service Bulletin 806980 3

Introduction

Purpose

This Field Service Bulletin gives the procedure for installing an internal machine interface

receptacle, cables, and voltage divider printed circuit board (PCB).

The systems and components shown are for reference. Your system could be different in

appearance.

Tools and materials

Assorted Phillips®, TORX®, and blade screwdrivers

Grounded wrist strap (or similar grounding accessory)

7 mm wrench (Powermax105/125 and Powermax105 SYNC only)

WARNING

ELECTRIC SHOCK CAN KILL

Disconnect electric power before doing installation or maintenance. You can

get a serious electric shock if electric power is not disconnected. Electric

shock can seriously injure or kill you.

All work that requires removal of the plasma power supply outer cover or

panels must be done by a qualified technician.

Refer to the Safety and Compliance Manual (80669C) for more safety

information.

NOTICE

Static electricity can cause damage to printed circuit boards (PCBs). Use correct

precautions when you touch PCBs.

Keep PCBs in antistatic containers.

Put on a grounded wrist strap when you touch PCBs.

Remove the plasma power supply cover and component barrier

1. Set the power switch on the plasma power supply to OFF (O), disconnect the power cord, and

disconnect the gas supply.

2. Remove the 16 screws from the plasma power supply cover.

3. Remove the plasma power supply cover.

WARNING

STORED ENERGY HAZARD

You can get a serious electric shock from the uncontrolled release of stored

energy in capacitors. Electric shock can seriously injure or kill you.

Before you remove the plasma power supply cover, disconnect electrical

input power and wait 1 minute to allow stored energy to discharge.

4. Remove the component barrier from the power-PCB side of the plasma power supply.

Remove the end panel bracket

Remove the end panel bracket . Some models have

2 screws on the end panel bracket that you must first

remove.

5. Make sure that the green and

yellow ground wire is at

the bottom of the machine

interface receptacle.

6. From the inside of the rear

panel, install the machine

interface receptacle in the

opening.

7. Install 2 screws (075534) in

opposite corners of the

machine interface receptacle,

as shown.

Torque the screws to 1.1 N·m

(10 in·lb).

8. Remove the screw that

attaches the green and

yellow ground wire from the

middle panel to the air filter.

9. Attach the green and yellow

ground wire from the machine

interface receptacle to the air

filter with the screw that you

removed in step 8.

Torque the screw to 1.7 N·m

(15 in·lb).

10. Make sure that the green and

yellow ground wire from the

middle panel is also attached

to the air filter with the screw

that you removed in step 8.

10 806980 Field Service Bulletin Powermax65/85/105/125, Powermax65/85/105 SYNC

11 . Attach the green ground wire from the voltage divider PCB to the middle panel. Use the

screw that is in the middle panel.

Powermax65/85 and

Powermax65/85 SYNC:

a. Install the ground wire

above the voltage divider

PCB and behind the

other cables, as shown.

b. Do you have the serial

interface port installed? If

you do, attach the green

and yellow ground wire

from the RS-485 serial

interface PCB to the

middle panel with the

same screw.

c. Torque the screw to

1.7 N·m (15 in·lb).

Powermax105/125 and

Powermax105 SYNC:

a. Remove the nut and

washer from the screw.

Use a 7 mm wrench.

b. Install the ground wire

above the voltage divider

PCB and behind the

other cables, as shown.

c. Do you have the serial

interface port installed? If

you do, attach the green

and yellow ground wire

from the RS-485 serial

interface PCB to the

middle panel with the

same screw.

d. Install the washer.

e. Torque the nut to 1.7 N·m (15 in·lb).
