6 Generac ® Pow er Systems, Inc. 1.8.1.1 Generator and Load Compatibility The generator must be fully compatible with the rated voltage, number of phases and frequency of the con- nected electrical loads. The generator , connected elec- trical devices, or both, can be damaged if voltage, num- ber of phases and frequency are not compatible.
1.1 0 ENGI N E OI L R E COMM EN D A TIONS The unit has been filled with 15W -40 engine oil at the factory . Use a high- quality detergent oil classified “F or Service CC, SD , SE or SF .” Detergent oils keep the engine cleaner and reduce carbon deposits.
8 Generac ® Pow er Systems, Inc. If an open bottom is used, the engine-generator is to be installed over non-combustible materials and should be located such that combustible materials are not capable of accumulating under the generator set.
Generac ® Pow er Systems, Inc. 9 Figure 2.1 – Basic Standby Electric System 2.2 EM ERGENCY CI RCU IT IS OL A TION M E THOD This prevents overloading the generator by keeping elec- trical loads below the wattage/amperage capacity of the generator .
10 Generac ® Pow er Systems, Inc. 2.7 B A T TER Y I NST ALL A TION Standby generators installed with automatic trans- fer switches will crank and start automatically when normal (utility) source voltage is r emoved or is below an acceptable preset level.
