Important Safety Instructions, Continued 



 

Be sure to disconnect all power sources before working on this equipment. 



 

If this equipment does not have a main power switch, the power plug serves as a 
readily operable disconnect device. 



 

Always pull on the plug or the connector to disconnect a cable. Never pull on the 
cable itself. 

Refer to this equipment’s specific installation instructions in this manual or in 
companion manuals in this series for connection to network ferro-resonant AC 
power sources. 

This section provides instructions for verifying that the equipment is properly 
grounded. 

Safety Plugs（USA Only）   

This equipment is equipped with either a 3-terminal (grounding-type) safety plug or 
a 2-terminal (polarized) safety plug. The wide blade or the third terminal is provided 
for safety. Do not defeat the safety purpose of the grounding-type or polarized safety 
plug. 
To properly ground this equipment, follow these safety guidelines: 

For a 3-terminal plug (one terminal on this plug is a protective grounding pin), insert 
the plug into a grounded main, 3-terminal outlet. 
Note: This plug fits only one way. If this plug cannot be fully inserted into the outlet, 
contact an electrician to replace the obsolete 3-terminal outlet. 

For a 2-terminal plug (a polarized plug with one wide blade and one narrow blade), 
insert the plug into a polarized mains, 2-terminal outlet in which one socket is wider 
than the other. 
Note:    If this plug cannot be fully inserted into the outlet, try reversing the plug.
