Installation
Outdoor Installation
Install the generator in a area that is free of debris, bystanders, and overhead obstructions. Make sure the generator is on secure level ground so that it cannot slide or shift around. Also install the generator in a manner so that the exhaust will not be discharged in the direction of nearby homes.
The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding.
Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear to engine and alternator parts.
CAUTION
Pay close attention to ventilation when operating the generator inside tunnels and caves.The engine exhaust contains noxious elements. Engine exhaust must be routed to a ventilated area.
Indoor Installation
Exhaust gases from diesel engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves.
Mounting
The generator must be mounted on a solid foundation (such as concrete) and set firmly on the foundation to isolate vibration of the generator when it is running.The generator must set at least 6 inches above the floor or grade level (in accordance to NFPA 110, Chapter
Generator Grounding
To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground (Figure 2).
Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.
NEC articles
1.Use one of the following wire types to connect the generator to earth ground.
a.Copper - 8 AWG (5.3 mm2)
b.Aluminum - 6 AWG (8.4 mm2)
2.When grounding the generator (Figure 2) connect the ground cable between the lock washer and the nut on the generator and tighten the nut fully. Connect the other end of the ground cable to earth ground.
3.NEC article
NOTICE
When connecting the generator to any buildings electrical system ALWAYS consult with a licensed electrician.
NOTICE
This generator has a permanent bonding conductor between the generator stator windings and the frame.
