1. Introduction 
This  manual  describes  all  the  information  needed  to  install  and  operate  an 
Eaton PV240, PV250, PV260 and PV270 grid-tie PV Inverter (“PV Inverter”). 
 
IMPORTANT 
In  order  to  avoid  problems  during  the  install  procedure,  it  is 
recommended to read the entire user manual before starting any 
install procedures. 
 
Any  improper  usage  may  result  in  damage  to  the  unit.  Therefore,  it  is

shock  during  maintenance  or  installation,  it  is  necessary  to 
ensure that all AC and DC terminals are disconnected. 
HOT SURFACE 
Although  inverter  is  designed  to  meet  international  safety 
standards,  the  surface  of  the  inverter  can  become  hot  during 
operation.  Therefore,  do  not  touch  the  heat  sink  or  peripheral 
surfaces during or shortly after operation.
