2 Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The gen- erator can operate safely , efficiently and reliably only if it is properly installed, operated and maintained.
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 volt- ages to the transfer switch as well as the standby generator .
4 1.1 GEN ER A T OR This equipment is a liquid- cooled, engine - driven gen- erator set. The generator is designed to supply elec- trical power that operates critical electrical loads during utility power failure. The unit has been facto- ry-installed in a weather resistant, all metal enclosure and is intended for outdoor installation only .
5 Figure 1.1 - Generator AC Connection System 1.6 MAI N CI RCU IT B R EAKER The generator’s main circuit breaker is included with the unit as shipped from the factory . The breaker for each unit is described in Figure 1.2. 1.7 GEN ER A T OR F U EL SY S TEM This unit has been factory tested and adjusted using a natural gas fuel system.
6 Figure 1.5- High Coolant T emperature Switch 1.8.3 L O W C OOL ANT LEVEL SWIT CH Should engine coolant level drop below the level of the high coolant temperature switch, it is possible for the engine to overheat without automatic shutdown. T o prevent such overheating without automatic shut down, the engine has a low coolant level sensor .

9 2.1 S T AN DB Y GEN ER A T OR I NS T ALL A TION Connecting this generator to an electrical sys- tem normally supplied by an electric utility shall be by means of a transfer switch, so as to isolate the electric system from the utility distri- bution system when the generator is operating.
10 2.4 B ASIC S T AN DBY ELE CTRIC SYST E M Figure 2.1 shows a schematic diagram of a basic standby electric system. Both the UTILITY power supply and the ST ANDBY GENERA TOR output are connected to an approved transfer switch.
11 2.8 GEN ER A T OR AC NEUTR AL CO N N EC T I O N S The manufacturer uses an UNGROUNDED AC neu- tral. Grounding is recommended only at the main service entrance. If the neutral wire is grounded and one of the phase loads becomes grounded, the exces- sive current opens the load circuit breaker or col- lapses the generator field.
12 2.1 0 ENGI N EER ED TR ANSF ER SWIT CH (2-WI R E S T ART G T S MODE) When required, the pre -packaged standby generator can be installed with an engineered W T ype transfer switch which controls utility voltage sensing, weekly exercising and load transferring .
13 Transfer Switch terminals N1 and N2 (also called Utility 1 and Utility 2) are the input utility AC power connections to the Transfer Switch. T ransfer Switch terminals T1 and T2 (also called Load 1 and Load 2) are the transfer switch AC output power terminals that go to the load circuit distribution panel.
14 The recommended battery is Group 26, 12VDC, 550 CCA/75 AH minimum. All batteries must be at 100 percent state - of- charge before they are installed on the generator . When using maintenance -free batteries, it is not nec- essary to check the specific gravity or electrolyte level.

16 3.3 ENGI N E G OVERNOR GAI N ADJ US TM ENTS Engine speed governing is also controlled by the engine control board. The engine governor has been set by the factory during final testing of the generator and should not be adjusted. If, however , adjustments are necessary , the following procedure should be followed (Figure 3.
17 6. Reduce load to 3/4, 1/2, 1/4 and no load. Decrease the stability pot if there is instability at any load point. 7. Adjust differential pot to make the recovery to load changes even faster and minimize load change undershoot and overshoot. If it is set too high, it may introduce oscillations at some load.
18 3.7 C ONTROL BO AR D DI P SWIT CH S E TTIN G S Located on the control board is an eight position DIP switch (see Figure 3.2). The eight different switches, are used to configure the control board for the spe- cific engine and governor being used and are pre - set at the factory .
19 7. T urn the voltage regulator’s VOL T AGE ADJUST pot to obtain a line -to -line voltage of: A. 240 V AC if the generator has been configured for 60 Hertz operation.
20 3. Install a new lower intake manifold gasket. 4. P osition the lower intake manifold to the cylinder head. 5. Install retaining bolts/studs finger tight. 6. Tighten all bolts/studs to specifications in the tightening sequence shown: • F irst pass = 7=10 N-m (5-7 lb -ft).
21 4 .7 .2 B A TT E R Y FL UID Check battery electrolyte fluid based on the Maintenance Schedule. Fluid should cover separa- tors in all battery cells. If fluid level is low , add dis- tilled water to cover tops of separators. DO NOT USE T AP W A TER IN BA TTERY .
22 5. Apply light coating of new engine oil to seal of new oil filter . Install FIL TER and tighten by hand only . DO NOT OVER TIGHTEN . 6. Remove OIL FILL CAP . Add recommended oil (see SPECIFICA TIONS). DO NOT FILL ABOVE THE DIPSTICK “FULL ” MARK.
23 4.9.3 BA TTER Y MAI NTENANCE The battery should be inspected per Section 4.7, Scheduled Maintenance. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary .
