static-sensitive devices. Standard electrostatic-sensitive component handling
precautions should be observed. Release the 4 corners of the interface board
from the standoffs by pressing down on the standoff locking tabs with a small flat-
headed screwdriver. Be careful to not apply any abnormal stress to the interface
board while performing this, as this may damage the interface board or control
board connectors.
6. Remove the interface board from the inverter.
7. Disconnect the communications cable from the interface board connector (TB1),
and pull the cable out through the access holes at the bottom of the inverter.
8. Locate the option ROM in the option ROM connector, labeled CN41, on the lower-
left side of the control PCB. Gently work the option ROM PCB up and down while
pulling on it until the ROM releases from the control PCB option ROM connector.
IMPORTANT NOTE: Do not remove the option ROM on inverter units that
were received from the factory with option ROMs pre-installed. Units that are
shipped from the factory with option ROMs pre-installed (H3 and 600V G3 units,
for example) require these ROMs for correct operation, and removal of the option
ROM may cause incorrect operation or inverter damage. If you are in doubt about
the requirement of an option ROM in your inverter unit, contact Toshiba
International Corporation for assistance.
9. Carefully re-install the operation panel and support bracket and tighten the 4
screws that attach the operation panel support bracket to the control board
support bracket.
10. Reinstall the inverter's cover (close and latch the door on units with hinged doors).
DANGER!
door open.
11. Turn all power sources to the inverter unit ON, and verify that the inverter functions
properly. If the inverter unit does not appear to power up, or does not function
properly, immediately turn power OFF. Repeat steps 1 ∼ 3 to remove all power
from the inverter. Then, verify all connections. Contact Toshiba International
Corporation for assistance if the problem persists.
12. To re-initialize the inverter after the ROM has been removed, perform a TYPE 3
reset. After the initialization sequence, display the value of the ROM VERSION
parameter in GROUP:UTILITY PARAMETERS. This number should match the
standard ROM version number that was recorded prior to option ROM installation.
If this parameter value does not match the value recorded earlier, contact Toshiba
International Corporation for further assistance.
