ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 f. Operating Procedures. (1) Prior to further operations, turn the LS MEP 113A generator set off. Place the LS Main Power AC circuit breaker on the Launcher Electronics module in the "OFF" position. (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) TO AVOID ELECTRICAL SHOCK HAZARD THE LOAD BANK MUST ALWAYS BE CONNECTED TO EARTH GROUND. Ground the load bankframe by connecting the #8 AWG (or larger) green or bare conductor, provided with the load bank, from the ground stud to the LS ground stake. TO AVOID ELECTRICAL SHOCK HAZARD THE LS GENERATOR SET MUST BE OFF WHILE MAKING ELECTRICAL INTERCONNECTIONS. Position the load bank to assure the remaining 4 conductors, provided with the load bank, will reach from the load bank load terminal board to the road side of the LS generator set. TO AVOID ELECTRICAL SHOCK CHECK THAT THE GROUND CONDUCTOR FROM THE LOAD BANK TO THE EARTH GROUND IS CONNECTED AND THE CONDUCTOR IS CONTINUOUS. Internally connect the load bank for a 33 KW 208V L-L 3P/4W Ioad in accordance with the reconnection procedure in TM 11-6625-3197-13&P. Raise the generator set electrical terminal access door on the set road side and secure in this position. Remove the plastic protective cover from the generator set electrical terminal assembly. Connect the white or gray #6 AWG (or larger) conductor from the LO terminal on the load bank input terminal board to LO on the generator set output load terminal board. Connect the remaining conductors from L1-L2-L3 on the load bank to L1-L2-L3 on the generator set. DO NOT ATTEMPT TO LATCH THE CLOSE GENERATOR SET DOOR. EQUIP- MENT DAMAGE COULD RESULT IF CAUTION IS NOT OBSERVED. Release the generator set terminal door so electrical terminals are not exposed. Close the latch on the load bank terminal access door. Place the load bank control circuit breaker in the "OFF" position. Start the LS generator set in accordance with TM 9-6115-464-12. Place the generator set circuit breaker switch in the “ON” position. operate the load bank in accordance with TM 11-6625-3197-13&P. Load the generator set to 100 (redline) on the generator set control panel percent power meter. Loaf the set starting at 0 and increasing the load with the load bank variable control and switches until the 100 percent point is reached. The time interval for each Ioad increment should be judged by engine stability. As the engine stabilizes at a given Ioad, the next load increment may be applied. 2-34
