Cabinet installation
When installing the SCALANCE W7x8 in a cabinet, you need to use detached antennas. A
suitable flexible conne

detached antenna are available from SIMATIC NET. You will find detailed information in
the section
Flexible connecting cables, antennas and accessories (Page 24).

frequency range,
the distance between the antennas connected to R1A1, R1A2, R1A3 and those
connected to R2A1, R2A2, R2A3 must be at least 1 m.
there may be wireless interference on one or both IWLAN interfaces if the transmit
power is higher than 15 dB.
