DANGER
Only qualified electricians or contractors should
!attempt such installations, which must comply strictly with applicable codes, standards and regulations.
1.1UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for damage.
•This standby generator set has been factory sup- plied with a weather protective enclosure that is intended for outdoor installation only.
If this generator is used to power electrical load circuits normally powered by a utility power source, it is required by code to install a trans- fer switch. The transfer switch must effectively isolate the electrical system from the utility dis- tribution system when the generator is operat- ing (NEC 700, 701 and 702). Failure to isolate an electrical system by such means will result in damage to the generator and also may result in injury or death to utility power workers due to backfeed of electrical energy.
If any loss or damage is noted at time of delivery, have the person(s) making the delivery note all damage on the freight bill or affix his or her signature under the consignor's memo of loss or damage.
If a loss or damage is noted after delivery, separate the damaged materials and contact the carrier for claim procedures.
“Concealed damage” is understood to mean damage to the contents of a package that is not in evidence at the time of delivery, but is discovered later.
1.2PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have to run for long periods of time with no operator pres- ent to monitor engine conditions. For that reason, the engine is equipped with the following systems that protect it against potentially damaging conditions:
1. | Low Oil Pressure Sensor | 3. | Overcrank |
2. | High Temperature Sensor | 4. | Overspeed |
There are LED readouts on the control panel to indi- cate that one of these faults has occurred. There is also a “System Set” LED that is described below.
1.3SYSTEM SET LED
The “System Set” LED is lit when all of the following conditions are true:
1.The AUTO/OFF/MANUAL switch is set to the AUTO position.
2.The utility voltage being supplied to the unit is being sensed by the Control PCB. If the utility sense voltage is not connected to the unit or if it is below 168 volts AC, then the system set light will flash rapidly. This indicates that if the AUTO/OFF/MANUAL switch is placed in the Auto position , the generator will start.
3.The “Not In Auto” dip switch is set to the OFF position on the control board.
4.No alarms are present, for example, low oil pres- sure, high temperature, etc.
