Note: 
 The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output 
reactor, output filter are optional parts. Please refer to Peripheral Optional Parts for 
detailed information.   
 A1 and A2 are optional parts.   
 P1 and (+) are short circuited in factory, if need to connect with the DC rector, please 
remove the contact tag between P1 and (+).
