Grounding

WARNING

Danger to life from overvoltage, fire hazard

When using outdoor antennas, the shared or even grounded pin of the circuit must be

connected to the shield of the coaxial cable and with all touchable conductive parts and

circuits. Otherwise, in the event of a fault there may be illegally high voltages on touchable

parts.

NOTICE

Damage to the device due to potential differences

To fully eliminate the influence of electromagnetic interference, the device must be

grounded. There must be no potential difference between the following parts, otherwise the

device or other connected device could be severely damaged:

• Housing of the SCALANCE W700 and the ground potential of the antenna.

• Housing of the SCALANCE W700 and the ground potential of a device connected over

Ethernet.

• Housing of the SCALANCE W700 and the shield contact of the connected Ethernet

cable.

Connect both grounds to the same foundation earth or use an equipotential bonding cable.
