4. Use the peel and stick area of the wrist strap to connect the wrist strap to an ESD mat (or to the top cover if an

ESD mat is not available). Place the wrist strap on your arm as indicated by the instructions for the wrist strap.

6. Pry out the PROM U9 using an IC extractor. Insert the hook, first into one slot and then the other, and gently

pry out the PROM. Place the PROM in the tube and close the tube.

7. Open the other end of the IC tube and remove the replacement PROM U9 from the tube.

8. Insert the PROM into the U9 socket, insuring the dot on the chip is oriented as shown in Figure 2.

9. Reclose the IC tube. Remove wrist strap and disconnect it from the BOP.

3.6 REASSEMBLY

1. Carefully line up the 14-pin header on Distribution board A6A1 with the corresponding socket on the front

panel, and the Distribution board LED’s with the corresponding cutouts in the front panel and press the Distri-

bution board into place.

2. Secure Distribution board A6A1 to the front panel using seven screws, seven lockwashers and five flat wash-

ers as noted during disassembly.

3. Slide the ADJUST knob over the shaft of the ADJUST control and secure using nut and washer. Press black

cover onto front panel ADJUST knob.

4. Carefully line up circuit breaker pins with corresponding connectors on front panel and carefully mate front

panel and chassis. If circuit breaker incorporates a Printed Circuit Board, it may be necessary to press the

PCB onto the circuit breaker.

CAUTION: Installing the inner screws first can result in damage to the front panel.

5. Attach front panel with Distribution board A6A1 to the chassis first using two outer screws at the bottom of the

chassis, then two inner screws.

6. Connect two 4-pin connectors (or one 4-pin and one 6-pin connector), and one 5-pin connector attached to

twisted pairs to connectors J12, J15 and J14, respectively on Distribution board A6A1 (see Figure 2). The 4-

pin connectors can plug into either J12 or J15; holding the wires, line up the pins on an angle, then push until

straight and press into place; if necessary a screwdriver can be used to apply enough pressure to front panel

to slightly increase separation between front panel and Distribution board A6A1, enough for the connectors to

be inserted.

7. Attach the fan connector (J10, Figure 2) by inserting the connector straight into the mating socket.

8. Connect ribbon cable from Distribution board A6 to Digital board connector A1J2.

9. Connect ribbon cable from A4A3 module to Distribution board A6A1 connector J11.

10. If Circuit breaker does not have a Printed Circuit Board, connect the four wires to the circuit breaker in accor-

dance with the tags on the wires.

11. Attach the cover to the chassis using 14 screws.

12. Attach the two mounting ears to the chassis using three screws for each.

13. Install the power cord, connect the unit to source power, turn on power supply and proceed to Initialization,
