External Cooling Fan Installation Precautions
•
When installing the new external cooling fan, note that the air intake for the external cooling fan’s ventila-
tion is on the top of the MxC.
•
When reconnecting the power lead for the external cooling fan, place it near to the hole for the lead wire on
the fan cover so the wire does not get pinched.
•
After the power lead of the external cooling fan is passed through the hole on the fan cover, attach the rub-
ber bushing.
•
There shouldn’t be an problems if connectors CN26 and CN27 are accidentally reversed when reconnect-
ing components. This is because CN26 and CN27 have the same electrical specifications.
