3.2
LED displays
Information on the operating status and data transfer of the SCALANCE W-788-xPRO/RR or W74x-
1PRO/RR
There are several LEDs on the front of the SCALANCE W788-xPRO/RR or W74x-1PRO/RR
that provide information its operating status:
Note
If the LED for the WLAN interface is not green when the device starts up, although it is
activated, the interface is not ready for operation (interface not initialized).
The main reason for this is usually that during commissioning of a SCALANCE
W788-
xPRO/
RR or W74x-1PRO/RR products, a waiting time of up to 15 minutes can occur when
the ambient temperature is below zero. The device is ready for operation at the specified
ambient temperature as soon as the LED for the WLAN interface is lit green.

still exists. If no primary user is detected, data traffic is possible again.
The wait time of 30 minutes is
necessary due to legal requirements and cannot be shortened
even by resetting the device.

Functions of the reset button
The reset button is on the rear of the device below the sealing screw directly beside the C-
PLUG and has several functions:
●Restart of the device
To restart the device, press the Reset button.
●Loading new firmware
If the normal procedure with the Load & Save menu of Web Based Management does not
work, the reset button can be used to load new firmware. This situation can occur if there
was a power outage during the normal firmware update.
●Restoring the default parameters (factory defaults)
●Adopting the configuration data from the PRESET PLUG.

Notes on operating the device in a hazardous area
WARNING
EXPLOSION HAZARD
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.
WARNING
Requirements for the cabinet/enclosure
To comply with EU Directive 94/9 (ATEX95), this enclosure must meet the requirements of
at least IP54 in compliance with EN 60529.

4.2
Securing the housing
Grounding terminal
WARNING
To operate the SCALANCE W788 safely, the housing must make contact with a chassis
ground cable. Do not use the SCALANCE W788 without a ground cable connected.
The ground cable can be connected to one of the securing screws. To allow this, several of
the screw contact surfaces in the housing do not have a powder coating. You will find these
contact surfaces on the right-hand side of the housing (when looking at the front of the
housing).
Wall mounting or standard rail
Note
Installation location
There are no restrictions regarding the installation location for the device.
Antennas, in particular directional antennas, must be mounted in keeping with their
characteristics (refer to the technical specifications of the antenna
--> Radiation pattern
d
iagrams).
There are two ways of securing the housing:
●Wall mounting
Use the holes in the housing to screw the device to the wall or on a horizontal surface.
●Standard rail mounting
Mount the SCALANCE W788-xPRO/RR or W74x-1PRO/RR on a 90 mm long, vertically
mounted section of standard rail (S7-300). In this case, the standard rail serves as an
adapter between the wall and SCALANCE W788-xPRO/RR or W74x-1PRO/RR. If you
want to mount the SCALANCE W788-xPRO/RR or W74x-1PRO/RR along with a PS791-
1PRO, you will require a 150 mm long standard rail.
Make sure that there is suitable strain relief for the connecting cable.

Drilling template
The location of the holes for wall mounting of the SCALANCE W788-xPRO/RR / W74x-
1PRO/RR is shown in the following diagram:
NOTICE
Premature aging of the device and cables due to UV radiation
For applications outdoors, the use of the hardware SCALANCE W786 is advisable due to
its greater suitability.
Protect the SCALANCE W788-xPRO/RR or W74x-1PRO/RR from direct sunlight by
providing suitable shade. This avoids unwanted heating of the device and prevents
premature aging of the device and cabling. When operating the SCALANCE W outdoors, it
must be mounted so that it is protected from UV.
UV radiation can discolor the front panel of the SCALANCE W788-xPRO/RR or W74x-
1PRO/RR. Discoloring of the front panel does not impair the mechanical stability of the
device. The device must also not be subjected to long periods of rain (provide cover to
protect from rain). The cover should be made of a synthetic material since metal impairs the
radiation of radio waves.
Note
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.
