Mounting Recommendations - Advantech SmartStart SL305 Hardware Manual

3. Router Design

3.6 Mounting recommendations

• It is possible to place the router on a flat surface,
• mount the router on a wall using four holes in corners (Figure ??) and screws with diameter 4 mm,
• attach the router on DIN rail EN 60715 with the included clip BB-SBD25.
The router meets EN 61439-1:2011 requirements/certifications for low-voltage switchgear and control
gear assemblies. These environments are described as:
• A non-public, industry environment of low voltage with high interference,
• a public environment of low voltage and without high interference.
For both of these environments, it is possible to mount the router to a switchboard, after which there is
no need to have examination immunity or issues in connection with EMC according to EN 61439-1:2011.
To comply with the EN 61439-1:2011 specification, follow these instructions:
• For whip antennas it is recommended to observe a minimum distance of 6 cm from cables and metal
surfaces on every side in order to avoid interference. When using an external antenna separate from
the switchboard it is necessary to fit a lightning conductor.
• When mounting a router on sheet-steel we recommend using a cable antenna.
• For all cables, we recommend to bind the bunch, and for this we recommend:
– The length of the bunch (the combination of power supply and data cables) should be a max-
imum 1.5 m. If the length of data cables exceeds 1.5 m or if the cable is leading towards the
switchboard, we recommend installing surge protectors.
– Data cables must not have a reticular tension of
• Sufficient space must be left between each connector for the handling of cables,
• To ensure the correct functioning of the router we recommend the use of an earth-bonding distribu-
tion frame for the grounding of the power supply of the router, data cables and antenna within the
switchboard.
