Equipment  Characteristics, Capabilities  and  Features a. Description: The PU 794/G con- sists of a modified M200A1 trailer chassis, auxiliary assemblages and a modified 15 kW, 60 Hz, generator set (MEP-004A). The modifications are not intended or designed to be removed. The modifications are as follows: (1) The PU 794/G is rated at 20 kW . (2) The engine generator assembly is mounted on shock isolator mounts to reduce noise transmission. (3) The fan and shrouding were replaced with an improved fan and guard for better cooling and noise reduction. (4) A muffler is added to a new combustion air intake filter housing and the exhaust system is modified to reduce noise. (5) The top of the set was raised to enclose the muffler and sound suppres- sion material is added to the inside of the  housing. (6) Devices for electromagnetic pulse protection (EMP) have been added. (7) A remote control unit for the PU 794/G is furnished for mounting inside a communications shelter and will start, stop and parallel two power units. The remote control unit indicates set running, contactor closed, low fuel and phase relation for paralleling. (8) To facilitate remote paral- leling, the PU 794/G has a remote speed- setting  isochronous  governor,  permissive paralleling relay, under- frequency and undervoltage  protective  devices,  associated control and power cables, junction boxes and switches. b. Features: The PU 794/G provides 20 kW, 60 Hz power and has noise reduc- tion to 65 db(A) in any direction when measured at seven meters. The unit is EMP  protected. The unit can be operated from the generator set controls or from the remote control unit. It can be operated as a single unit or paralleled with another PU 794/G for load transfer. Two PU 794/G’s are not to be continu- ously operated in parallel. The power unit can be operated while being towed. 1-9.
