WARNING 

To  avoid  an  electric  shock  hazard,  after  the  input 
and  control  power  is  removed  from  the  drive  and 
the  AC  Regen,  wait  five  (5)  minutes  for  Bus 
capacitors  to  fully  discharge  (DC  Bus  capacitors  of 
the  drive  and  the  AC  Regen).    Verify  that  the 
voltage  on  the  bus  capacitors  has  discharged  by 
measuring  the  DC  bus  voltage  at  the  +DC  &  –DC 
terminals of the drive. The voltage must be zero.

 

 
 

Fuse Check

: 

Check all fuses. Do not replace any fuse before performing the following checks. Please note if an on-board 
fuse (soldered to the control board) is open, do not attempt to replace it. An open on-board fuse indicates a 
damaged board.  
 

Visual Check: 

Check all fuses, boards, wire harnesses, connectors, bus bars and enclosure walls for discoloration 
 

Ohmic Check

: 

Check IGBT personality boards for the following: 

-

 

Burnt or discolored resistors R1, R2, & R3 (6 sets per Regen)  

-

 

Shorted D1 & D2 using meter set for diode check (6 sets per Regen). 

These personality boards are either soldered or screwed on the IGBT’s (power transistors).
