To reassemble the device, proceed as follows:
• Carefully insert the boards into the case. The mounting locations are shown in
Figures 3-3 to 3-8. For the model of the device designed for surface mounting, use
the metal lever to insert the processor circuit board CPU board. The installation is
easier with the lever.
• First plug the plug connectors of the ribbon cable into the input/output boards I/O
and then onto the processor module CPU. Do not bend any connector pins ! Do not
use force !
• Insert the plug connector of the ribbon cable between the processor module CPU
and the front cover into the socket of the front cover. This action does not apply to
the device version with detached operator panel. Instead the plug connector of the
ribbon cable connected to a 68-pole plug connector on the rear side of the device
must be plugged into the plug connector of the processor circuit board CPU. The 7-
pole X16 connector belonging to the ribbon cable must be plugged behind the D-
subminiature female connector. The plugging position is not relevant in this context
as the connection is protected against polarity reversal.
• Press the latches of the plug connectors together.
• Replace the front cover and secure to the housing with the screws.
• Mount the covers.
• Re-fasten the interfaces on the rear of the device housing. This activity is not nec-
essary if the device is designed for surface mounting.
Depending on the version, the device housing can be

/ or / (Figure 3-25 and Figure 3-26) there are 4 covers and 4 holes for securing the

device, with housing size
• Remove the 4 covers at the corners of the front cover, for size
located centrally at the top and bottom also have to be removed. Thus the 4 respec-
tively 6 elongated holes in the mounting flange are revealed and can be accessed.
• Insert the device into the panel cut-out and fasten it with four or six screws. For di-
mensions refer to Section 4.26.
• Mount the four or six covers.
• Connect the ground on the rear plate of the device to the protective ground of the
panel. Using at least one M4 screw. The cross-section of the line, here used, must
correspond to the maximal connected cross-section, at least 2.5 mm
• Connections use the plug plug terminals or screw terminals on the rear side of the
device in accordance to the circuit diagram. When using forked lugs for direct con-
nections or screw terminal, the screws, before having inserted the lugs and wires,
must be tightened in such a way that the screw heads are even with the terminal
block. A ring lug must be centered in the connection chamber, in such a way that
the screw thread fits in the hole of the lug. The SIPROTEC 4 System Description
provides information on wire size, lugs, bending radii, etc. which must be observed.
