ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 Do not attempt to connect the paralleling cable while either or both of the sets to be paralleled is operating. Make sure that there is no input to the load from another source. Failure to observe this warning may result in death by electrocution. Precise generator sets equipped with the electric governor system cannot be paralleled with sets that have the electrohydraulic governor system. Equipment damage could result If caution is not observed. NOTE Prior to attempting parallel operation, ensure all generator sets have the same fre- quency and voltage output. a. If the generator sets are to share a Ioad greater than the KW rating of a single set, connect load terminal boards as shown in Figure 2-4. This arrangement allows for sharing or transferring of the load between generator sets. b. Open the left access door to the set compartment and remove the safety cover from the terminal board (Figure 1-5). c. Insert load Ieads through plate and sleeve assembly (Figure 1-5) located to the left of the generator set air in- take. NOTE The Ioad terminal boards will accommodate 2-wire single phase and 4-wire three phase loads. One or more single phase loads can be served alone or in combinations with three phase loads; but the load on any one phase must not exceed 100 percent of the current rating of that phase. Be sure that wire sizes are correct for Ioad to be carried. d. Connect the load to terminals marked L1, L2, L3, and L0 (Figure 2-4). NOTE Make certain that the load terminal boards of the sets to be paralleled are con- nected properly. Reading left to right, phase rotation for the phase loads is L1, L2, L3. Be sure L1 is connected to L1, L2 is connected to L2, ect. e. Connect load leads and paralleling cables as shown in Figure 2-5 and Figure 2-6. After Ioad connection, install safety cover. NOTE tighten binding nuts with plastic/phenolic box end wrench and NOTE Paralleling of tactical precise generator sets requires that paralleling cables be installed and the shorting plug located on one of the paralleling receptacles of each generator set be removed. 2-12
