18.  In LIST mode,voltage set and current set button can’t be used,In LIST 
STATE item,choose LIST>OFF will enable you to quit list mode. 
 
 
3.10 OVP function 
IT6700 series power supply provide OVP function, press  (Shift)+  
button can enable you to set the over voltage protection level.Over voltage may 
caused by internal defect or customer’s incorrect operation(such as output 
voltage rising),or a too high external voltage.Once OVP function is triggered,the 
output will be off immediately and “OVP” indicator light will be lit,the VFD 
display “OVER VOLT”. 
Avoid external voltage that across the output terminals exceeding the 120% of 
rated voltage or it will damage out power supply! 
When power supply in OVP state,please check the external factors first, after 
you exclude the external factors, press ON/OFF button to open output again.If 
in communication state originally, you should by sending order OUTP ON order
