a line side contactor and a generator side contactor. The contactors are both electrically and mechanically interlocked. An automatic taper battery trickle charger (40 MA max) and a seven day electronic exerciser clock are installed in the A.T.S. as standard equipment. The A.T.S. also contains the power failure sensing circuitry necessary to send a start/stop signal to the engine generator set. TESTING POLICY: Before any generator is shipped from the factory, it is fully checked for performance.
The engine manufacturer has established an excellent world-wide engine service organization; engine service is available from a nearby authorized dealer or distributor; check the yellow pages of the telephone directory under “engines,” or ask the dealer from whom you purchased the power plant. The rated power of each engine-generator is limited by the temperature, altitude and all other ambient conditions specified by the engine manufacturer. Engine power will decrease 3-1/2% for each 1000 ft.
INSTALLATION inform you of the engine’s requirements and assist in making you aware of the decisions you must make. In no case should the instructions or information provided be interpreted to conflict with any local, state or national codes. If in doubt, always consult your local fire marshal or gas supplier.

Three Phase FIGURE 5 The standby generator terminals in the A.T.S. are marked “GENERATOR - G1, G2, G3 and G-N. The “hot” leads G1 G2 and G3 wire directly to the generator side contactor, terminals G1, G2 and G3. The G-N connection is made to the lug on the standoff just to the right of the generator side contactor. The line terminals in the A.T.S. are marked “LINE - L1, L2, L3 and L-N”. The “hot” leads L1, L2 and L3 will wire directly to the top lugs on the line side contactor.
Because of the many different types of service, feeder, and distribution equipment, no specific wiring instructions can be provided. It is recommended that only copper wire be used. In all cases it is essential that while the load is connected to the generator, there can be absolutely no feedback from the generator to the power line or the power line to the generator. When properly installed, the normal A.T.S. Control and safety systems will eliminate all paths for feedback.
