Wiring Instructions 

A qualified electrician needs to know the following before wiring: 
1.  The amperage rating of the electrical box should be adequate. Refer to the  Technical Specifications 

(page 4) for this information. 

2.  The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. 

Refer to the motor nameplate, on the side of motor, for this information.  

NOTE:  The  wiring  used  must  be  rated  for  the  motor  nameplate  voltage.  Refer  to  local  codes  for 
recommended wire sizes, correct wire size, and maximum wire run; undersize wire causes high-amp draw 
and overheating to the motor. 

Grounding 

WARNING

 

 

This machine must be grounded while in use to protect the operator from electrical shock. This 
compressor is equipped with an electrical cord that has an equipment grounding conductor and a 
grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed and 
grounded in accordance with ALL local codes and ordinances. 

 

DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper receptacle 
installed by a qualified electrician. 

 

CHECK with a qualified electrician or service person if you do not completely understand the 
grounding instructions, or if you are not sure the tool is properly grounded. 

 

Risk of electrical shock.

 In the event of a short circuit, grounding reduces the risk of shock by 

providing and escape wire for the electric current. This air compressor must be properly grounded. 

 

Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be 
installed by a qualified electrician. 

 

Repairs to the cord set or plug MUST be made by a qualified electrician. 

Grounding Instructions 

The  portable  air  compressor  is  equipped  with  a  cord  having  a  grounding  wire  with  an  appropriate 
grounding plug.  

1. 

The cord set and plug with this unit contains a grounding pin. This 

plug MUST be used with a grounded outlet.  

 

IMPORTANT: The outlet being used must be installed and 

 

grounded in accordance with all local codes and ordinances.  

2. 

Ensure the outlet being used has the same configuration as the 

grounded plug. DO NOT USE AN ADAPTER. 

3. 

Inspect the plug and cord before each use. Do not use if there are 

signs of damage. 

4. 

If these grounding instructions are not completely understood, or if 

in doubt as to whether the compressor is properly grounded, have the installation checked by a 
qualified electrician.
