Device damage due to signal cable damage during removal
Signal cables can become damaged when the power block is removed. This can cause the
device to fail.
• When removing the power block, ensure that you do not damage any signal cables.
• Disconnect the second plug-in connection of the fiber-optic cables only after the power
block has been withdrawn a little way (see step 7).
Installation is performed the same as removal, but in the reverse order.
Note
Specifications for the installation
The tightening torques specified in the "Tightening torques for screw connections" table must
be observed.
Carefully insert the plug
-in connections and ensure that they are secure.
The fiber optic cable connectors must be re
-installed at their original slot. The fiber optic
cables and sockets are labeled accordingly (U11, U21, U31) for correct as
signment.
