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 W and the ground potential of the antenna.
• Housing of the SCALANCE W and the ground potential of a device connected over Ethernet.
• Housing of the SCALANCE W and the shield contact of the connected Ethernet cable.
Connect both grounds to the same foundation earth or use an equipotential bonding cable.
If it is used outdoors, the device must always be connected to protective earth.
Notice for USA/Canada (UL Requirements)
When an external antenna or the device itself is located outdoor:
- The Ethernet-Port (RJ45) is considered a TNV-1 circuit (according IEC 60950-1). Connected
Ethernet circuits must fulfill TNV-1 requirements (SELV circuits are not sufficient).
- The device must be properly earthed at the chassis earthing terminal.
- The 12 – 24 V power supply lines of the device are considered a TNV-1 circuit. Connected power
supply circuits must fulfill TNV-1 requirements. The PS791-2AC power supply may be connected
directly to 100 – 240 C AC primary circuits. The 100 – 240 AC wiring system must be conducted
to conduits. This wiring system (including conduits) shall be secured before installation of the
product, for example by using an outlet box, according to NEC or CEC.
When the device is located indoor:
- The Ethernet Port (RJ45) is considered a SELV circuit (according IEC 60950-1). All connected
Ethernet circuits must fulfill SELV requirements and shall be entirely contained within a single
low-voltage power distribution and within a single building.
- Do not connect any external LAN-circuit, powersupply or antenna coming from outdoor.
