meaning:
2.3
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.

CAUTION
Minimum distance to antennas
Fit the device so that there is a minimum clearance of 20 cm between antennas and
persons.
WARNING
If a device is operated in an ambient temperature of more than 50 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so
that it is only accessible to service personnel or users that are aware of the reason for
restricted access and the required safety measures at an ambient temperature higher than
50 °C.
WARNING
When used in hazardous environments corresponding to Class I, Division 2 or Class I,
Zone 2, the device must be installed in a cabinet or a suitable enclosure.
General notes on use according to ATEX and IECEx
WARNING
To comply with EC Directive 94/9 (ATEX95) or the conditions of IECEx, this enclosure or
cabinet must meet the requirements of at least IP54 in compliance with EN 60529.

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 also 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
The requirements of EN61000

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:
•Grounding pin of the SCALANCE W700 and the ground potential of the antenna.
•Grounding pin of the SCALANCE W700 and the ground potential of a device connected
over Ethernet.
•Grounding pin 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.
