• Remove the 4 covers at the corners of the front cover. That exposes the 4 elongated holes in the mounting
bracket.
• Insert the device into the panel cut out and fasten it with 4 screws. For dimensions refer to section 4.10.
• Mount the 4 covers.
• Connect the earth on the rear plate of the device to the protective earth of the panel. Use at least one M4
screw for the device earth. The cross-sectional area of the earth wire must be equal to the cross-sectional
area of any other control conductor connected to the device. The cross-section of the earth wire must be at
least 2.5 mm
• Connections are realized via the plug terminals or screw terminals on the rear side of the device according
to the circuit diagram.
For screw connections with forked lugs or direct connection, before inserting wires the screws must be tight-
ened so that the screw heads are flush with the outer edge of the connection block.
A ring lug must be centred in the connection chamber, in such a way that the screw thread fits in the hole of
the lug.
The SIPROTEC 4 System Description has pertinent information regarding wire size, lugs, bending radii, etc.
Installation notes are also given in the brief reference booklet attached to the device.
