Introduction and Installation Notes 

 

HIGH VOLTAGE – Risk of Electrical Shock. This equipment is connected to 

line voltage that can create a potentially hazardous situation. 

  Always make certain power is off before servicing this equipment. 

  Do not connect control circuits to T3. 

  Do not connect a ground or neutral to T3. 

 

  Make sure static phase converter and equipment are properly grounded. 

 

  Wire recommendation is based on the use of copper wire.  If using aluminum wire, use the 

copper equivalent for current amount. 

 

  For indoor use. 

 

  Humming and clicking noise is normal when power is applied to converter. 

 

  Installation of this equipment must comply with all national, state and local electrical codes. 

 

  Installation must be performed by qualified licensed electrician who should have 

experience working with this line voltage.
