Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH  
FROM INCORRECT GROUNDING WIRE CONNECTION: 
Check with a qualified electrician if you are in doubt as to whether the outlet is properly 
grounded.  Do not modify the power cord plug provided with the compressor.   

Never remove the grounding prong from the plug.  Do not use the compressor if the power cord or plug is 
damaged.  If damaged, have it repaired by a service facility before use.  If the plug will not fit the outlet, have 
a proper outlet installed by a qualified electrician.

110-120 VAC Grounded Compressors: 
Compressors with Three Prong Plugs

1.  In the event of a malfunction or breakdown, 

grounding provides a path of least resistance for 
electric current to reduce the risk of electric shock.   
This compressor is equipped with an electric 
cord having an equipment-grounding conductor 
and a grounding plug.  The plug must be 
plugged into a matching outlet that is properly 
installed and grounded in accordance 
with all local codes and ordinances.

2.  Do not modify the plug provided –  

if it will not fit the outlet, have the proper 
outlet installed by a qualified electrician.

3.  Improper connection of the equipment-grounding 

conductor can result in a risk of electric shock.  
The conductor with insulation having an outer 
surface that is green with or without yellow 
stripes is the equipment-grounding conductor.  
If repair or replacement of the electric cord or 
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.

4.  Check with a qualified electrician or service 

personnel if the grounding instructions are 
not completely understood, or if in doubt as to 
whether the compressor is properly grounded.

5.  Use only 3-wire extension cords that have 

3-prong grounding plugs and 3-pole receptacles 
that accept the compressor’s plug.

6.  Repair or replace damaged or 

worn cord immediately.
