b. Engines.  For  description  of  the  Military  Stan- dard Engines refer to TM 5-2805-258-14. c. Generators. (1) Generator  Set  Model  MEP-017A.  The generator (fig. 1-1) provided with the Model MEP- 017A generator set has a 2-pole rotor with a brush- less  rotating  exciter  rotor  section  mounted  on  the same  shaft.  The  generator  is  rated  at  5  kw  (kilo- watts), 0.8 pf (power factor), 60 HZ (hertz) at 3,6000 rpm (revolutions per minute). The generator output characteristics are as follows: 120/240 volts, single phase, two wire; 120 volts, three phase, three wire; and 120/208 volts, three phase, four wire. (2)  Generator  Set  Model  MEP-022A.  The generator (fig. 1-3) provided with the model MEP- 022A generator set has a 14-pole rotor with a brush- less  rotating  exciter  rotor  section  mounted  on  the same shaft. The generator is rated at 5 kw, 0.8 pf, 400 hz at a speed of approximately 3428 rpm. The generator output characteristics are as follows: 120/ 240  volts,  single  phase,  two  wire;  120  volts,  three phase,  three  wire;  and  120/208  volts,  three  phase, four wire. d. Control Boxes.  The control box for each of the generator  sets  is  similar.  They  contain  the  neces- sary controls, instruments and other electrical com- ponents that are required for operation of the elec- trical portion of the generator sets. 1-10. Tabulated Data a.  Identification.  The  generator  sets  are  pro- vided  with  three  identification  plates.  The  infor- mation contained on thses plates and their location is as follows: (1)  U.S.  Army  Identification  Plate. This plate is located on the top of the control box bracket near the tool box. It specifies: Generator set model number. Stock No. (number). Generator set serial No. Mfr.  (manufacturer). Generator model number. Operating volts, ph (phase) amp (amperes) kw   kilowatts),   kva   (kilovolt-amperes),   pf TM 5-6115-332-14 P-8-614-14 TO  35C2-3-424-1 (power factor), cy (cycles) or hz (hertz) and rpm   (revolutions   per   minute).   Cont.   No. (contract number). Lg   (length),   width,   hgt   (height),   and   wt (weight).  Eng  mfg  (engine  manufacturer) model, and ser No. (2)  Generator  Nameplate.   The plate is lo- cated on the right side of the generator stator hous- ing   at   a   point   above   the   support   bracket.   It specifies: NSN (National stock number) KW  (kilowatts). Cps or Hz (cycles per second or hertz). PF (power factor). Mfr  (manufacturer). Serial No. (number). (3)  Engine  Nameplate.   The engine plate is located on the upper side of the flywheel housing. It contains  information  on  the  manufacturer,  model, nomenclature, National stock number and displace- ment. b.  Wiring  Diagram.  Refer  to  figure  FO-1  and FO-2  for  the  wiring  diagram  for  the  Model  MEP- 017A generator set and to figure FO-3 and FO-4 for the wiring diagram for the Model MEP-022A gener- ator set. c. Engine Electrical System.  The engine elec- trical system functions in conjunction with several of the generator set controls and other components. The system is of the 24-volt, negative, ground-type. d. Dimensions and Weight. (1)   Model   MEP-017A.   For   dimensions   and weight, refer to figure 1-1. (2)   Model   MEP-022A.   For   demensions   and weight, refer to figure 1-3. e. Base Plan. The  base  plan  provides  dimensions for a base that may be prepared in advance of the in- stallation  of  the  generator  set.  The  base  may  be  con- structed of wood planking or a concrete pad may be prepared, as desired. For the base plan, refer to fig- ure 1-5. 1-7
