TM 9-6115-604-34 NAVFAC P-8-633-34 WARNING Generator set must be shut down and MAINTENANCE LOCKOUT switch S1OO set to MAINTENANCE during following procedures. Generator GI output lines TI, T2, 13, LI. L2, and L3 must be momentarily grounded to remove static potentials that may be present on the lines. Failure to follow these procedures may result In death by electrocution. WARNING Generator set output power cable assemblies must be disconnected from output terminals and "parked" on standoff Insulator assemblies during the following procedures. Failure to do so may result In death by electrocution. (1) Remove (a) Shut down generator set in accordance with Operator and Organizational Maintenance Manual. Be sure MAINTENANCE LOCKOUT switch S100 has been set to MAINTENANCE. (b) Disconnect generator set output power cable assemblies from generator set terminals and apt the cables on their standoff insulator assemblies. (c) Go into the generator compartment and remove cabinet B rear access panel in accordance with the Operator and Organizational Maintenance Manual. (d) Using a grounding stick with a grounded metal tip, momentarily touch the lugs of generator G1 leads T1, T2, T3, L1, L2, and L3 where they connect to load circuit breaker CB1 01. See Figure 1 03. (e) Reinstall rear access panel on cabinet B. Remove cabinet A rear access panel in accordance with the Operator and Organizational Maintenance Manual. (f) Tag and disconnect wires from terminals of transformer T104 or T106 through T110 to be replaced. (g) See Figure 10-5. Remove hexagon head capscrews (9) and lockwashers (10) to remove any transformer T104 or Tl06 through T 1 0 (11). (h) Remove fuse (12), if good, and store in generator set tool box for future use as a spare. (2) Install (a) See Figure 10-5. Install transformer T104 or T106 through T1 0 (11) so that fuse dips are on the left and secure with lockwashers (10) and hexagon head capscrews (9). (b) Install fuse (12) in fuse dips of transformer (11). (c) Make wiring connections to transformer terminals as tagged. Remove and discard tags. (d) Reinstall rear access panel on cabinet A. g. KVAR MeterTransformerTi05. KVAR meter transformer T105 is mounted on the left wall inside the upper front section of cabinet B. Because the transformer receives voltage inputs of 416 V ac from transformers T104 and T106, the generator set must be shutdown before transformer T105 can be safely worked on. 10-15
