2 Generac ® Pow er Systems, Inc. Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with this Installation, Start -up and Adjustment Manual and with the unit. The generator can operate safely , efficiently and reliably only if it is properly installed, operated and maintained.
Generac ® Pow er Systems, Inc. 3 ELE CTR ICAL HA Z AR DS • All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages to the transfer switch as does the standby generator when it is in opera- tion.
1.1 I NTRODUCTION T O I NST ALL A TION NOTE: Read the entire manual before starting the installa- tion. Ensure that the model number of the unit being installed matches a model on the front cover .
1.3 B EFOR E I NS T ALLA TION Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Circuit Isolation Method” and “T otal Circuit Isolation Method” in Sections 1.8 and 1.9 (P age 11) carefully .

Generac ® Pow er Systems, Inc. 19 2.3 SE QU ENCE OF AUT OMA TIC OP ER A TION The generator’s control panel houses a control logic circuit board. This board constantly monitors utili- ty power source voltage. Should that voltage drop below a preset level, circuit board action will signal the engine to crank and start.
20 Generac ® Pow er Systems, Inc. 6. T o crank and start the engine, set the Auto/Off/Manual switch to MANU AL. 7. Let the engine stabilize and warm up for a few minutes. 8. Set the generator’s main circuit breaker to its ON (or closed) position. The standby power source now powers the loads.

T urn OFF the utility power supply to the transfer switch using the means provided (such as the utility main line circuit breaker).
Generac ® Pow er Systems, Inc. 23 Do not attempt manual transfer switch operation until all power voltage supplies to the transfer switch have been positively turned off. Failur e to turn off all power voltage supplies will result in extr emely hazardous and possibly fatal electrical shock.
