o 4. Gate Drive Board Replacement (8510A-A04/A06 Only)
a) Assure that all power has been removed and 30 seconds has elapsed.
b) Remove the front cover from the drive. Refer to the ESD precaution
on page 1 and apply grounding wrist strap.
Important: The supplied grounding wrist strap must be worn during
this procedure to protect the IGBT gate leads against ESD damage.
c) Label and remove any cables from the I/O Board. Remove the I/O
Board (with Display & Keypad Module) by taking the four screws
out and carefully separating the connectors.
d) Label and remove any cables from the CPU Board. Remove the six
screws securing the CPU Board. Remove board.
e) Label and remove any cables from the Gate Drive Board. Remove the
board by taking out the six screws securing it.
Tip: For easier board removal, lift the board off of the three
interconnect boards. Move the lower right side of the board under the
mounting lip and slide it out the bottom of the drive.
f) Install the new board and re-connect cables. Assure that the Gate
Drive Board is properly seated with the Power Board via the
Interconnect Boards.
Important: Do Not touch the gold edge connectors on the
Interconnect Board – contamination could result, causing poor
connections. In addition, ESD could damage the IGBT gate leads.
g) Replace the CPU and I/O (with Display & Keypad Module) Boards.
Assure that the board connectors are fully seated and any cables
previously removed have been re-connected.
h) Replace drive cover and remove wrist strap. Check for proper
operation.
