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.
