TM 9-6115-604-34NAVFAC P-8-633-34(f)Tag and disconnect wires from transformer terminals.(g)Refer to Figure 10-4. To remove current transformers CT10 or CT12 (4), remove hexagonal nuts (1),lockwashers (2), and cable insulator spacer (3).(h)To remove current transformers CT114 (8) or CT11 (9), remove hexagonal nuts (5), lockwashers (6), andcable insulator spacer (7).(i)Remove cable insulator spacers (10) or threaded rods (11) only if damaged.(1).Install(a)Refer to Figure 10-4. Install threaded rods (11) or cable insulator spacers (10), if removed.(b)Install current transformers CTI1 (9) and CT1 14 (8) over generator lead T2 and secure with cable insulatorspacer (7), lockwashers (6), and hexagonal nuts (5).(c)Install current transformers CT1 0 and/or CT12 (4) over generator leads T3 and/or T1, respectively, andsecure with cable insulator spacers (3), lockwashers (2), and hexagonal nuts (1).(d)Make wiring connections to current transformer terminals as required.(e)Connect lugs of generator leads T1, T2, and T3 to appropriate terminals on load circuit breaker CB1 01.Refer to Figure 10-3.(f)Install the wraps as necessary to secure generator leads and relieve stress from their lugs.(g)Reinstall cabinet B rear access panel in accordance with the Operator and Organizational MaintenanceManual.b.Ground Fault Transformer Ti00. Ground fault transformer T1 0o is mounted in the lower rear section of cabinetA. The transformer sits on the sheet metal weldment that houses the generator set output terminals. Nomaintenance shall be done in this cabinet when generator set output power cables are connected to theirterminals. The cables should be "parked' on their standoff insulator assemblies to prevent their bringing in lethalvoltages from any external, energized bus they may be connected to.WARNINGGenerator set must be shut down and MAINTENANCE LOCK-OUT swatch S1O set toMAINTENANCE during following procedures. Failure to observe this warning may result Indeath by electrocution.WARNINGGenerator set output power cable assemblies must be disconnected from output terminalsand "parked" on standoff Insulator assemblies during following procedures. Failure to do somay result In death by electrocution.(1)Remove(a)Shut down generator set in accordance with Operator and Organizational Maintenance Manual. Be sureMAINTENANCE LOCKOUT switch S100 has been set to MAINTENANCE.(b)Disconnect generator set power output cables from generator set output terminals and "park" the cables onthe standoff insulator assemblies.(c)Go into the generator compartment and remove cabinet A rear access panel in accordance with theOperator and Organizational Maintenance Manual.(d)Tag and disconnect wires connected to transformer T100 terminals.(e)Refer to Figure 10-5. Remove hexagon head capscrews (1) and lockwashers (2) to remove ground faulttransformer T100 (3).10-7
