PROCESSOR TECHNOLOGY CORPORATION Sol POWER SUPPLY SECTION II Position FWB3 (MDA980-l) on power supply subchassis as shown in drawing on Page X-2. BE SURE NEGATIVE (-) TERMINAL OF FWB3 is next to transformer. Insert a 6—32 x. ½ binder or pan head screw from bottom of subchassis, place #6 lockwasher on screw and secure with 6—32 hex nut. *( ) Step 34. Connect blue transformer wires to unmarked terminals of FWB3. *( ) Step 35. Install large (2½”) mounting ring for C9 (54,000 ufd capacitor) on side wall of power supply subchassis as shown in drawing on Page X-2. Position ring over the three mounting holes in the side wall of subchassis so the clamping screw faces the bottom of subchassis and so it will be accessible from the Sol—REG end of the subchassis. Insert three 6—32 x ½ binder or pan head screws from outer side of side wall through the mounting holes. Place #6 lockwasher on each screw and secure with 6-32 hex nut. Figure 2-5 shows an assembled Sol-20 power supply subchassis. Figure 2-5. Sol—20 power supply subchassis assembly. (Rear of subchassis at left.) ( ) Step 36. Install small (1½”) mounting ring for C8 (18,000 ufd capacitor) as shown in drawing on Page X—2. (Step 36 continued on Page 11—17.) Rev B 11—16
PROCESSOR TECHNOLOGY CORPORATION Sol POWER SUPPLY SECTION II Position ring over the two mounting holes located between FWB3 and the Sol-REG so that the clamping screw is positioned between the transformer and FWB3. Insert two 6-32 x 1/2 binder or pan head screws from bottom side of chassis through the mounting holes. Place #6 lockwasher on each screw and secure with 6-32 hex nut. (Refer to Figure 2-4.) ( ) Step 37. Route Sol-PC power cable between C8 mounting ring and the transformer, mount C8 in its mounting ring, and tiqhten clamping-screw. (See Figure 2-4.) ( ) Step 38. Connect white wire of C8 cable to negative (-) terminal of C8 and green wire to positive (+) terminal of C8. (This cable was soldered to the Sol-REG when you assembled it.) Remove terminal screws, place #1O lockwasher on each screw, place cable lugs on screws and drive screws tightly into appropriate terminals. *( ) Step 39. Mount C9 in its mounting ring with its "+" terminal slightly toward C8 and tighten clamping screw. (See Figure 2-5.) *( ) Step 40. Prepare R13 (39 ohm 2 watt) for installation on C9. Solder a #10 lug to each lead of R13. Bend leads of R13 to fit the terminals of C9. (R13 should fit on C9 as shown in Figure 2-5.) *( ) Step 41. Connect Sol-20 DC power cable (5 wire) and R13 to C9. Route cable between C8 and transformer. Remove terminal screws from C9. Place lockwasher, terminal screw, blue lead of Sol-20 DC cable and one R13 lead on one terminal screw and drive it into the positive (+) terminal on C9. Attach lockwasher, white cable lead and other R13 lead to negative (-) terminal on C9 in the same manner. Tighten both capacitor terminals tightly. CAUTION - - LOOSE CONNECTIONS ON C9 CAN LEAD TO ARC- ING AND SUBSEQUENT POWER SUPPLY DAMAGE. *( ) Step 42. Connect blue pigtail of Sol-20 DC cable to positive (+) terminal of FWB3. (This pigtail has a spade lug at its free end and is connected to the lug you just attached to the positive terminal of C9.) Connect white pigtail of Sol-20 DC cable to negative (-) terminal of FWB3. (This pigtail has a spade lug at its free end and is connected to the lug you just attached to the negative terminal of C9.)
