Data in Section 4.25.
• Connect the earth of the device to the protective earth of the panel. The cross-sec-
tional area of the earth wire must be equal to the cross-sectional area of any other
conductor connected to the device. The cross-section of the earth wire must be at
least 2.5 mm
2
.
• Connect solid, low-impedance operational earthing (cross-sectional area ≥ 2.5
mm
2
) to the earthing surface on the side. Use at least one M4 screw for the device
earth.
• Make the connections according to the circuit diagram via the screwed-type termi-
nals. Fibre-optic cables and electrical communication modules are connected at the
inclined housings. The SIPROTEC
