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.

Securing the housing
Grounding terminal
WARNING
Operation of the W7x8 only with connected ground cable
To operate the SCALANCE W7x8 safely, the housing must make contact with a chassis
ground cable. Do not use the W7x8 without a ground cable connected.
The chassis ground cable is fixed with a screw. On the rear of the device there is an M4
threaded hole for this purpose.
Installation options
To install the W7x8, you have the following options:
●Wall mounting
●Installing on the S7-300 standard rail
●Installing on a DIN rail
CAUTION
Danger of injury by falling objects
If the SCALANCE W7x8 is subjected to strong vibration (> 10 g), mounting on a 35 mm DIN
rail does not provide adequate support. Under such conditions, the device can come out of
the mounting and may cause injury.
In this case, install the device on an S7-300 standard rail or on a wall.
Strain relief for the cables
Regardless of the type of installation, make sure that there is suitable strain relief for the
connecting cable.
Installation location
There are no restrictions regarding the installation location for the device. Antennas, in
particular directional antennas, must be mounted according to their characteristics.
Note
-
If you are installing outdoors, use the SCALANCE W786.
-
The minimum distance to fluorescent lamps should be 0.5 m.
-
When installed in a cabinet, we recommend that you do not install relays on the same or on
directly neighboring mounting rails.

Lightning protection, power supply and grounding
Notes on 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 is 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.

Safety extra low voltage
WARNING
Danger to life from overvoltage, fire hazard
SCALANCE W700 devices are designed for operation with a directly connectable safety
extra-low voltage or with the power supply adapters available as accessories (available
only for the SCALANCE W786 device). Therefore only safety extra-low voltage (SELV) with
limited power source (LPS) complying with IEC950/EN60950/VDE0805 may be connected
to the power supply terminals.
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).
The power supply unit to supply the SCALANCE W700 must comply with NEC Class 2
(requirements of class 2 for power supply units of the "National Electrical Code, table 11
(b)") or SELV with LPS (Limited Power Source) EN 60950-1. If the power supply is
designed redundantly (two separate power supplies), both power supplies must meet these
requirements.
Exception:
Power supply with PELV (according to VDE 0100-410 or IEC 60364-4-41) is also possible if
the generated rated voltage does not exceed the voltage limits 25 VAC or 60 VDC.
WARNING
Transient overvoltage
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).
