Disconnect the plugs for the fiber optic cables and signal cables (5 plugs).
3.
Remove the DRIVE-CLiQ cables and connections to the CU320 (5 plugs).

Remove the retaining screws for the slide-in electronics unit (2 screws).
When removing the slide-in electronics unit, you have to disconnect 5 further plugs one

When removing the fan, ensure that you do not damage any signal cables.
The Control Interface Board can then be removed from the slide-in electronics unit.
CAUTION
When removing the connector of the ribbon cable, make sure that you actuate the locking
lever on the connector very carefully (e.g. with a screwdriver) otherwise the lock could be
damaged.
Installation
For re-installation, carry out the above steps in reverse order.
CAUTION
The tightening torques specified in the table "Tightening torques for connecting current-
carrying parts" must be observed.
Carefully re-establish the plug connections and ensure that they are secure.
When dealing with connectors with a lock, make sure that the locking lever is securely
engaged once connected.
The screwed connections for the protective covers must only be tightened by hand.
