TM  5–6115-584-12 NAVFAC   P–8-622-12 TO-35C2-3-456-1 TM-05682C-12 CHAPTER  2 OPERATING  INSTRUCTIONS Section  I.  OPERATING  PROCEDURE 2-1. GENERAL. a.   This   chapter   contains   instructions   for   operation, power  and  control  connections.  Location  and  function  of controls and indicators, and safety precautions are also pro- vided. b.  Refer  to  table  3-2  and  perform  “Before  Operation” Preventive  Maintenance  Checks  and  Services  before  operat- ing the Generator Set. c. CAUTION If set will be idle for some time, disconnect the negative battery lead. Be sure to reconnect when load is placed on set. Table  2-1  describes  the  Generator  Set  controls  and instruments (see figure 2-3). WARNING All   personnel   involved   in   the   operation   or maintenance   of   the   Generator   Set   should become thoroughly familiar with the safety pre- cautions   prior   to   performing   operation   or maintenance procedures. Prior to connection of load cables, make sure all switches are in OFF or OPEN position, the Gen- erator Set is not operating. Inspect  the  Generator  Set  ground  connection prior  to  starting  the  unit.  Electrical  defects  in load lines or load equipment can cause death by electrocution  when  contact  is  made  with  an ungrounded  system. Do not smoke or carry an open flame when ser- vicing   the   batteries   or   fuel   tank.   Exercise extreme care to prevent electrical arcing in the area of the batteries. Battery  electrolyte  contains  sulfuric  acid  and can cause severe burns. Handle it with care. If the electrolyte comes in contact with the body, eyes, or clothing, rinse immediately with clean water. Avoid spilling electrolyte on painted sur- faces. Do not work alone or smoke when servic- ing  batteries. Do  not  operate  Generator  Set  in  an  enclosed area  unless  the  exhaust  gases  are  piped  to  the outside. Continued breathing of exhaust fumes is dangerous. 2-2. 2-3. Stay  clear  of  all  exposed  electrical  terminals when  Generator  Set  is  operating. Remove  all  rings,  watches  and  other  jewelry when  performing  maintenance  on  this  equip- ment. Loose fitting clothing should be secured to prevent it from catching in moving parts. POWER CONNECTIONS. WARNING BEFORE   ATTEMPTING   TO   CONNECT LOAD CABLES, MAKE SURE THE GENER- ATOR   SET   IS   NOT   OPERATING.   ALL SWITCHES  ARE  IN  THE  OFF  OR  OPEN POSITION. To connect load cables to Generator Set, attach load leads to terminals located in output control box, as required. See figures 2-1 and 2-3. NOTE For  120V,  1  PH  operation  connect  safety ground (generally green) and neutral (white) to L-1. Connect the hot wire (black) to L-3. EOUIPMENT  RECONNECTION. Before operating unit, be certain voltage and frequency rat- ing  of  the  load  matches  that  of  the  Generator  Set.  If  the output  voltage  of  the  Generator  Set  must  be  changed  to match a particular load, rotate reconnection switch located on  Reconnection  Panel  to  desired  output  connections.  See figure  2-2. 2-4.   STARTING  GENERATOR  SET  (SEE  FIGURE  2-3). CAUTION Do not idle engine. Operate generator set only at rated RPM. Do not use either to aid starting generator set. Do not operate in excess of 200 hours continu- ous with JP-4, MIL-J-5624 bulk fuel. a. When starting a set with a dry fuel filter drain or change: (1) Push in the DC circuit breaker. system or after a Change  9 2-1
