PROCESSOR TECHNOLOGY CORPORATION Sol POWER SUPPLY SECTION II ( ) Step 23. Set Sol-REG to one side. 2.7.3 ( ) ( ) ( ) *( ) ( ) ( ) Power Supply Subchassis Assembly and Test Step 24. Mount transformer (T1 for Sol-lo, T2 for Sol-20) on power supply subchassis (L-shaped chassis). Position transformer as shown in drawing on Page X-2 and attach it to the subchassis with three 8-32 x 1/2 binder or pan head screws, #8 lockwashers and 8-32 hex nuts. Insert screws from bottom and outer side of chassis as shown. Place lockwasher on each screw and secure loosely with hex nuts. Slide transthe chassis and former as close as possible to the edge of tighten nuts. NOTE -- Only one of the holes in the side wall is used. Use the one that lines up with the transformer mounting tab. Step 25. Prepare ( ) Twist the two two inches at transformer leads. black wires together except for the last the commoning block lug end. ( ) Twist the two green wires together for their full length. ( ) Twist the two length. yellow wires together for their full *( ) Twist the two blue wires together for their full length. Step 26. Connect Sol-PC power cable (4-wire cable which connects to J10 on Sol-PC) to Sol-REG. Tin ends of cable and solder green lead to pad X9, white lead to pad X1, red lead to pad X7 and white-yellow lead to pad X8. Step 27. Connect Sol-20 DC power cable (5 wire) to Sol-REG. Tin ends of cable and solder white lead to pad X4 (above R8), red-white lead to pad X5 (between C5 and FWB2) and yellowwhite lead to pad X6 (left of C5). Step 28. Connect transformer leads to Sol-REG. ( ) Solder green leads to pads T1 and T2, white-yellow lead to pad T3 and yellow leads to pads T4 and T5 on Sol-REG circuit board. Step 29. Prethread the three Sol-REG heat sink mounting holes in the power supply subchassis shown in drawing on page X-2 with #6 x 5/16 sheet metal screws. Remove screws. Rev B II-14
PROCESSOR TECHNOLOGY CORPORATION Sol POWER SUPPLY SECTION II ( ) Step 30. Place #4 lockwashers on two 4-40 x 3/16 binder or pan head screws. Insert these screws from the bottom side of the power supply subchassis through the two mounting holes located near the middle of the bottom of the power supply subchassis, one on each side. Place another *4 lockwasher on the screws and drive each screw tightly into a 4—40 x ¼ tapped spacer. ( ) Step 31. Position Sol—REG PC board with top edge over the previously installed spacers. Place #4 lockwashers on two 4—40 x 3/16 binder or pan head screws and drive screws t through Sol-REG board into spacers. ( ) Step 32. Attach heat sink on Sol—REG to power supply subchassis as shown in drawing on Page X-2. At this point use only the two side screws which you used in Step 29 to pre— thread the holes. (The middle screw will be installed later.) Place a #6 lockwasher on each screw before driving it through the sink into the subchassis. Figure 2—4 shows an assembled Sol—lO power supply subchassis. Figure 2—4. Sol-lO power supply subchassis assembly. (Rear of subchassis at left.) *( ) SteP 33. Install bridge rectifier FWB3 on power supply subchassis. (Step 33 continued on Page 11-16.)
