Installing and Removing the CP 440

When installing and removing the CP 440, you must observe certain rules.
Tool
For installing and removing the CP 440 you require a 3.5 mm cylindrical
screwdriver.
Installation Sequence
To install the CP 440 on a rack, proceed as follows:
1. Remove the filler panel from the slot you want to use by gripping it where
marked and pulling it toward you.
2. Insert the CP 440 module and tilt it downward.
3. Screw the module down at the top and bottom with a torque of
0.8 ... 1.1 Nm.
Removal Sequence
To remove the CP 440 from the rack, proceed as follows:
1. Undo the screws at the top and bottom of the module.
2. Tilt the module upward and remove it.
3. Replace the filler panel over the empty slot.
Note
The CP 440 can be hot-plugged and hot-pulled, in other words with voltage
applied. This means that the CP 440 can be replaced while the programmable
logic controller is in operation.
To avoid the CPU going into STOP, OB 83 (insert/remove interrupt) and OB 122
(I/O access error) must be programmed.
The CP 440 is parameterized automatically once it has been inserted. The CP 440
then resumes operation.
