CONNECTION

wBefore the generator can be connected to a build-ing’s electrical system, a licensed electrician mustinstall an isolation (transfer) switch in the build-ing’s main fuse box. The switch is the connectionpoint for generator power and allows selection ofgenerator or main line power to the building. Thiswill prevent the generator from charging the mainpower line (backfeeding) when the main powersupply has failed or has been turned off for linerepair. Backfeeding can electrocute or injure linemaintenance personnel. Also, generator and build-ing electrical system damage can occur when nor-mal operating power returns if unit is used withoutan isolation switch.

AE00086

EXTENSION CORD NOTES9 When using an extension cord, its total length

should not exceed60 meters for cross section of 1.5 mm squareand100 meters for cross section of 2.5 mm square.

9 This extension cord should be protected by atough flexible rubber sheath (IEC 245) or theequivalent to withstand mechanical stresses.

1 Choke knob

NOTE:The choke is not required to start a warm engine.Push the choke knob in to the original position.

4. Pull slowly on the recoil starter until it is engaged,then pull it briskly.

5. After the engine starts, warm up the engine untilthe engine does not stop when the choke knob isreturned to the original position.

6. Push the choke knob back to the original position.

NOTE:When starting the engine in areas where the ambienttemperature is below 0°C (32°F), the engine automati-cally operates at the rated r/min (3,600 r/min) for threeminutes to warm up the engine regardless of the econ-omy control switch position. The economy control unitoperates normally afterwards if the economy controlswitch is turned to “I” (ON).

Overload indicator lightThe overload indicator light 1 comes on when anoverload of a connected electrical device is detected,the inverter control unit overheats, or the AC outputvoltage rises. The electronic breaker will then activate,stopping power generation in order to protect the gen-erator and any connected electric devices. The ACpilot light (green) will go off and the overload indicatorlight (red) will stay on, but the engine will not stop run-ning.

When the overload indicator light comes on and powergeneration stops, proceed as follows:1. Turn off any connected electric devices and stop

the engine.2. Reduce the total wattage of connected electric

devices within the application range.3. Check for blockages in the cooling air inlet and

around the control unit. If any blockages arefound, remove.

4. After checking, restart the engine.

NOTE:9 The generator AC output automatically resets

when the engine is stopped and then restarted.9 The overload indicator light may come on for a

few seconds at first when using electric devicesthat require a large starting current, such as acompressor or a submergible pump. However, thisis not a malfunction.
