9. Insert needle nose pliers into the opening for one of the snaps and use the pliers to squeeze it together.

10. Place a blade screwdriver against the raised rib next to the snap and gently turn the screwdriver to push the panel

away from the base.

Figure 4

11 . Place another screwdriver or similar object into the opening between the panel and the base to keep the first corner

of the panel from re-engaging the snaps when you release the other corner.

Figure 5

12. Repeat step 9 and step 10 on the other corner of the panel.

Power Cord Replacement

Remove the power cord (CSA)

The power cord has a black wire and a white wire that connect to the power switch and a green ground wire that

connects to the heatsink.

1. Remove the black and white wires from the top of the power switch. You can use needle nose pliers or a straight

screwdriver to ease them off, if necessary.

Figure 7

2. Remove the screw that holds the ground wire to the heatsink. A notch in the power board provides access to the

screw. (See Figure 8.)

Figure 8

3. On the outside of the power supply, loosen the power

cord’s strain relief nut (see Figure 9) so that the wires

move freely.

4. From outside of the power supply, pull the wires

through the strain relief and through the hole in the rear

panel to remove the power cord.

5. Are you replacing the strain relief?

 If yes, use an adjustable wrench to unscrew the

retention nut on the inside of the power supply.

Remove the strain relief from the rear panel.

 If no, continue with Install the new power cord

(CSA).

Power Cord Replacement

Install the new power cord (CSA)

1. Are you installing a new strain relief?

 If yes, insert the strain relief into the rear panel and tighten the retention nut onto the strain relief. Loosely tighten

the strain relief nut on the outside of the power supply onto the strain relief.

 If no, continue with the next step.

2. Route the power cord wires through the strain relief nut and strain relief.

3. Press the connector for the black wire onto the pin on the upper left side of the power switch. Press the connector

for the white wire onto the pin on the upper right side of the power switch.

4. Tighten the green ground wire to the heatsink with a torque setting of 17.28 kg-cm (15 inch-pounds).

5. Press the wires into the track going up the side of the rear panel.

Powermax30/30 XP/30 AIR Field Service Bulletin 805430 11

Power Cord Replacement

Remove the power cord (CE)

1. Remove the blue and brown wires from the power switch. You can use needle nose pliers or a straight screwdriver to

ease it off, if necessary.

2. Remove the screw that holds the green/yellow ground wire to the heatsink. A notch in the power board provides

access to the screw.

Figure 10

3. On the outside of the power supply, loosen the

power cord’s strain relief nut so that the wires move

freely.

4. Remove the power plug from the old power cord.

5. From the inside of the power supply, pull the wires

through the strain relief and the hole in the rear

panel. (You cannot remove the wires from outside

the power supply because of the ferrite bead

installed on the wires.)

6. Are you replacing the strain relief?

 If yes, use an adjustable wrench to unscrew the

retention nut on the inside of the power supply.

Remove the strain relief from the rear panel.

 If no, continue with Install the new power cord

(CE).

Install the new power cord (CE)

1. Are you installing a new strain relief?

 If yes, insert the strain relief into the rear panel and tighten the retention nut onto the strain relief. Loosely tighten

the strain relief nut on the outside of the power supply onto the strain relief.

 If no, continue with the next step.

2. Route the wires for the power cord through the strain relief from the inside of the rear panel.



Because the power cord includes the ferrite bead, you cannot route the power cord

through the strain relief from the outside of the power supply. Do not remove the ferrite

bead from the power cord wires.

3. Press the connector for the brown wire onto the pin on the upper left side of the power switch.

4. Press the connector for the blue wire onto the pin on the upper right side of the power switch.

5. Tighten the green/yellow ground wire to the heatsink with a torque setting of 17.28 kg-cm (15 inch-pounds).

6. Press the wires into the track going up the side of the rear panel.

Reinstall the rear panel

1. Push the rear panel into the base to re-engage the snaps.

2. Verify the hole in the ground wire clip is aligned with the screw holes in the rear panel and the power supply.

3. Tighten the retaining screw with a torque setting of 8.1 kg-cm (7 inch-pounds).

4. Reconnect the ground wire to the ground wire clip.

5. Tighten the strain relief nut on the power cord.

6. Hold the component barrier so that the edge with the long cutout and the two notches is closest to the rear panel,

and the edge with the three notches is closest to the front panel.

7. A perforated line runs across the top of the barrier, about 25 mm (1 inch) below the top edge. Fold the barrier along

this perforation so that the top edge bends away from you.

8. Position the barrier so that the folded section will cover the top of the power board. The edge with the long cutout

and the two notches should align with the front panel; the edge with the three notches should align with the rear

panel.

9. Put the front-panel edge of the barrier in place first, then the rear-panel edge. The notches on each side of the barrier

should align with the ribs on the inside of the front and rear panels. As you slide the barrier into place, make sure the

bottom edge is in the same track the cover rests in.

10. Being careful not to pinch any wires, slide the cover onto the power supply. Align the bottom edges with the tracks,

and align the slot in the top of the cover with the tab on the front panel so that the louvers in the cover are in front of

the fan.

11 . Realign the front panel with the power supply.

12. Realign the rear panel with the power supply, making sure that the hole in the ground clip is aligned with the screw

holes in both the panel and the power supply.

13. Position the handle over the holes in the top of the cover, and position the ends of the handle underneath the edges

of the panels.

14. Reinstall the 2 screws that attach the cover and handle with a torque setting of 23.0 kg-cm (20 inch-pounds).

15. Reconnect the gas supply and power cord, and set the power switch to ON (I).
