WARNING: 

if the ground is defeated, certain fault conditions in the unit or in the system to 

which it is connected can result in full line voltage between chassis and earth ground. severe 

injury or death can then result if the chassis and earth ground are touched simultaneously.

the symbols shown above are internationally accepted symbols that warn of 

potential hazards with electrical products. the lightning flash with arrowpoint in 

an equilateral triangle means that there are dangerous voltages present within 

the unit. the exclamation point in an equilateral triangle indicates that it is 

necessary for the user to refer to the owner’s manual.

these symbols warn that there are no user serviceable parts inside the unit. 

do not open the unit. do not attempt to service the unit yourself. refer all 

servicing to qualified personnel. opening the chassis for any reason will void
