Value: Mains V 
Mains voltage. Average from all three phases. 
NOTE:  
The ratio between the voltage measured at the input terminals and the displayed 
voltage is adjusted by the setpoint Vm VT ratio.  
 
Value: Bus V 
Bus voltage. Average from all three phases. 
NOTE:  
The ratio between the voltage measured at the input terminals and the displayed 
voltage is adjusted by the setpoint Vb VT ratio.  
 
 
Value: Mains V L1-L2 
Mains voltage phase L1 to L2. 
Value: Bus V L1-L2 
Bus voltage phase L1 to L2. 
 
Value: Mains V L2-L3 
Mains voltage phase L2 to L3. 
Value: Bus V L2-L3
