Expanding the device and assigning the device parameters
7.1 Opening and closing the backplane cover
SIMATIC IPC477E PRO
76 Operating Instructions, 08/2017, A5E39912462-AA
Damaging the seal when opening
If the device has not been opened for a long time, the backplane cover and terminal
compartment cover may stick to the enclosure due to the seal. Opening the device with
excessive force or with tools will destroy the seal. Spray and water jets as well as
penetrating substances can then damage the device.
Open the backplane cover and terminal compartment cover gently, without applying too
much pressure.
1. Loosen the two indicated M4x16 screws of the terminal compartment cover ② (the
screws are captive in the covers).
2. Open the connection compartment cover
② and set it safely aside. (see also section
"Power supply (Page 44)").
3. Remove the green connection terminal. The connection terminal is plugged in and can be
pulled out from the front.
4. Loosen the eight M4x16 screws of the backplane cover
① (the screws are captive in the
covers).
