3.1.3.4 Mounting with Detached Operator Panel
Caution!
Be careful when removing or plugging the connector between device and detached operator panel
Non–observance of the following measure can result in property damage. Without the cable the device is not
ready for operation!
-never pull or plug the connector between the device and the detached operator panel during operation while
the device is alive!
For mounting the device proceed as follows:
• Fasten device of housing size
1
/
2
with 6 screws and device of housing size
1
/
1
with 10 screws. For dimen-
sions see for the Technical Data, Section 4.27.
• 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 maximum connected cross-sec-
tion, at least 2.5 mm
2
.
• Connections are realized via the plug or screw terminals on the rear side of the device according to the circuit
diagram. When using forked lugs for screw terminals or in case of direct connections, the screws must be
screwed in so far that the screw heads align with the terminal block before inserting the lugs and wires. 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 regarding maximum wire size, torque,
bending radius and cable relief and must be observed.
For mounting the operator panel please observe the following:
• Remove the 4 covers on the corners of the front plate. Thus, 4 respectively elongated holes in the mounting
bracket are revealed and can be accessed.
• Insert the operator panel into the panel cut-out and fasten with four screws. For dimensions see Technical
Data.
• Replace the 4 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 maximum connected cross-sec-
tion, at least 2.5 mm
2
.
• Connect the operator panel to the device. Then plug the 68-pin connector of the cable belonging to the op-
erator panel into the corresponding connection at the rear side of the device (see SIPROTEC 4 System De-
scription).
