DCA150SSVU — INSTALLATION
NOTE
Outdoor Installation
Install the generator in a area that is free of debris,
bystanders, and overhead obstructions. Make sure the
generatoris onsecure levelground sothat itcannot slideor
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
oftheinsulationandwillresultinshortcircuitsandgrounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.
Article250(Grounding)oftheNational ElectricalCode(NEC)
provides guide lines for proper grounding and specifies that
thecablegroundshallbeconnectedtothegroundingsystem
of the building as close to the point of cable entry as
practical.
NEC articles 250-64(b) and 250-66 set the following
groundingrequirements:
1. Use one of the following wire types to connect the
generatorto earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 2) connect the
ground cable between the lock washer and the nut on
thegenerator and tightenthenut fully.Connecttheother
end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried aminimumof 8ft.intotheground.
