Removal. 2-5 1-5 3-5 2-4 1-4 3-4 (1) Reconnection Switch (S6) and Transformers (CT1 and CVT1). Due to the large number of wires connected to these items, they are removed from the control box with the wiring connected. Remove screw (3, figure 6-10) and lockwashers (4). Remove screws (5), nuts (8), lockwashers (7) and spacers (6). Remove switch (1) and wiring. Remove transformers (6 and 7, figure 6-9) by removing screws(l), nuts(3) and lockwashers (2). Tag and remove wiring from transformers and switch. Disassemble transformers by removing screws(4) and nuts(5). (2) Load Terminal Board (TB1) (see figure 6-9). Disconnect load from load terminal board. Remove six screws (8) and lockwashers (9), attaching board (10) to control box (24) and remove board. Tag and disconnect four wires to load terminals (25). (3) AC Circuit Breaker (CB1). Remove side access panel (13, figure 6-9) by removing screws (11) and lockwashers (12). Tag and remove leads connected to circuit breaker (9, figure 6-10). Remove six screws (10) attaching breaker (9) to front panel (2) and remove breaker. (4) 15 Amp Circuit Breaker (CB3) (see figure 6-10). Remove side access panel (13, figure 6-9). Tag and disconnect two elec- trical leads to 15 amp circuit breaker (11, figure 6-10). Remove TM-0568C-34 two screws (12) attaching breaker to front panel of output con- trol box (2) and remove breaker. (5) Convenience Receptacle (J14). Remove four screws (11, figure 6-9) and lockwashers (12) attaching side access cover (13) to output control box and remove cover. Remove four screws (14, figure 6-10) and nuts (15) attaching receptacle cover to front panel and remove cover (16) and gasket (17). Tag and discon- nect two leads from receptacle. Remove two screws (18) and nuts (19) attaching receptacle to front panel and remove recep- tacle (13). Disconnect two leads from the receptacle and tape each lead end, separately (figure 1-7). (6) Linear Reactor (L1) (see figure 6-9). Remove side ac- cess panel (13). Tag and disconnect six leads to linear reactor (15). Remove four screws (14) attaching reactor to side panel of output control box and remove reactor. (7) Connector Assemblies (see figure 6-9). Remove screws (16 and 19) and nuts (17 and 20) attaching connectors (18 and 21) to output control box and remove connector. Tag and discon- nect wires from wiring harness to connector. Reconnect tagged wires to new connector. (8) Bridge Rectifier Assembly (see figure 6-9). Tag and remove leads to rectifier assembly (23). Remove nuts (22) holding bridge assembly to ac output control box and remove bridge assembly. Replace bad diodes or resistors as necessary. d. Install. (1) Load Terminal Board (TB1). Attach four tagged wires to load terminals per wiring diagram, figure 1-7. Attach load terminal board (10, figure 6-9) to control box (24) with six screws (8) and lockwashers (9). (2) AC Circuit Breaker (CB1) (see figure 6-10). Attach cir- cuit breaker (9) to front panel of output control box with six screws (10). Attach six tagged leads to terminals 3,4,7,8, 11, and 12 of breaker per wiring diagram, figure 1-1. Replace side access panel. (3) 15 Amp Circuit Breaker (CB3) (see figure 6-10). Attach new breaker (11) to front panel of output control box (2) with two screws (12). Attach two tagged leads to 15 amp circuit breaker per wiring diagram, figure 1-1. Change 4 6-17
