Security information
Siemens provides automation and drive products with industrial security functions that
support the secure operation of plants or machines. They are an important component in a
holistic industrial security concept. With this in mind, our products undergo continuous
development. We therefore recommend that you keep yourself informed with respect to our
product updates. Please find further information and newsletters on this subject at:
http://support.automation.siemens.com.
To ensure the secure operation of a plant or machine it is also necessary to take suitable
preventive action (e.g. cell protection concept) and to integrate the automation and drive
components into a state-of-the-art holistic industrial security concept for the entire plant or
machine. Any third-party products that may be in use must also be taken into account.

Lightning protection
WARNING
Danger due to lightning strikes
Antennas installed outdoors must be within the area covered by a lightning protection
system. Make sure that all conducting systems entering from outdoors can be protected by
a lightning protection potential equalization system.
When implementing your lightning protection concept, make sure you adhere to the VDE
0182 or IEC 62305 standard.
Suitable lightning protectors are available in the range of accessories of SIMATIC NET
Industrial WLAN:
● Lightning protector LP798-1N (order no. 6GK5798-2LP00-2AA6)
● Lightning protector LP798-2N (order no. 6GK5798-2LP10-2AA6)

Note
We recommend that you use the maintenance
-free lightning protector LP798-2N.
Exception: When there is a
lso DC power supplied via the antenna cable. In this case, only
the
lightning protector LP798-1N can be used.
WARNING
Danger due to lightning strikes
Installing this lightning protector between an antenna and a SCALANCE W700 is not
adequate protection against a lightning strike. The LP798-1N lightening protector only
works within the framework of a comprehensive lightning protection concept. If you have
questions, ask a qualified specialist company.
Note

Supply voltage
WARNING
Safety extra low voltage
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS).
This means that only SELV / LPS (Limited Power Source) complying with IEC 60950-1 / EN
60950-1 / VDE 0805-1 must be connected to the power supply terminals or the power
supply unit for the equipment power supply must comply with NEC Class 2, as described by
the National Electrical Code (r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
WARNING
Transient overvoltages
Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).

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.

Note
Galvanic isolation of the power supply unit
To ensure die
lectric strength according to IEEE 802.3, the supplying 24 V power supply unit
must be ga
lvanically isolated with a dielectric strength of 1500 VAC. The galvanic isolation
must a
lso not be bridged by other devices connected to the same power supply unit.
SCALANCE W774/W734 RJ-45
For the power supply, there are two options with the SCALANCE W774/W734:
● Direct feed in via the four-pin socket (position ①)
● Power over Ethernet via the RJ-45 Ethernet interface P2 (position ②). The other
Ethernet interface P1 is not capable of PoE.

The two following variants are available for power supply via an Ethernet cable:
●
IEEE 802.3at type 1 (IEEE 802.3af)
On an 8-wire Fast Ethernet cable, the power is supplied via the free data wires 4, 5, 7
and 8. This corresponds to alternative B according to IEEE 802.3af.
●
IEEE 802.3 at type 2
The power supply is known as phantom power via the wire pairs carrying signals (1/2 and
3/6).

Operating Instructions, 09/2015, C79000-G8976-C325-06 35
5.7
Replacing the PLUG (C-PLUG or KEY-PLUG)
How it works
If a new C-PLUG or KEY-PLUG with a valid license is inserted in a SCALANCE W786, the
configuration stored locally on the device is saved on the PLUG.
If an incorrect PLUG, for example from another product or a damaged plug is inserted, the
device signals an error with the red LED. The user then has the choice of either removing
the PLUG again or selecting the option to reformat the PLUG.
In terms of the PLUG, the WLAN devices work in two modes:
● Without PLUG
The device stores the configuration in internal memory. This mode is active when no
PLUG is inserted.
● With PLUG
The configuration stored on the PLUG is displayed over the user interfaces. If changes
are made to the configuration, the device stores the configuration directly on the PLUG
and in the internal memory. This mode is active as soon as a PLUG is inserted. As soon
as the device is started with a PLUG inserted, the SCALANCE W700 starts up with the
configuration data on the PLUG.
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether or not a PLUG is inserted at one second intervals. If it is
detected that the PLUG was removed, there is a restart.
If a KEY-PLUG was inserted in the device, the device changes to a defined error state
following the restart. With SCALANCE W, the available wireless interfaces are deactivated
in this case.

Removing the PLUG
Figure 5-1 Position of the slot for PLUG on the top of the SCALANCE W774/734
Follow the steps below to remove a PLUG from the device:
1. Turn off the power to the device.
2. Release the screw slot cover (position ①) and swing the slot cover to the side (position
②).
3. Insert a screwdriver between the front edge of the PLUG (Position ③) and the slot and
release the PLUG.
4. Remove the PLUG from the slot.
5. Screw the cover back onto the device.
Inserting the PLUG
Follow the steps below to insert a PLUG in the device:
1. Turn off the power to the device.
2. Release the screw slot cover (position ①) and swing the slot cover to the side (position
②).
3. The housing of the PLUG has a protruding ridge on the long side (position ④). The slot
has a groove at this position. Insert the PLUG correctly oriented into the slot. The PLUG
is correctly inserted when it is completely inside the device and does not jut out of the
slot.
4. Close the slot cover (position ②).
5. Tighten the screw at position ① to secure the slot cover.
