5.2 Installation notes
Make sure that at least 30 mm of clearance is left above the module.
A space of 35 mm must be provided beneath the module to route the
cables for the interfaces and for the power supply.
5.2.1 Mounting the router on the top-hat rail
The device is intended for mounting on a top-hat rail to DIN EN 50022.
Pull the top-hat rail downwards, at the same time pushing the device
back onto the top-hat rail. To remove the device, unhook it upwards,
and while pushing it up, lift it from the top-hat rail.
5.2.2 Functional earthing of the Internet Access Router
For functional earthing, make a connection between the "Functional
earth" terminal on the housing of the router and the equipotential
bonding of the control cubicle.
The connection "Functional earth" serves purely operational functions
(modem function).
Make sure that the cross-section of the interconnecting line does not
exceed 4 mm

5.3 Installation guidelines
•
The specified maximum operating temperature pertains to the air
temperature beneath the router (air inlet).
•
Observe a sufficient clearance to devices emitting strong
electromagnetic radiation (such as frequency converters,
transformers, motor controllers, etc.). The clearance between these
devices and the Internet Access Router should be as large as
possible. If necessary install partition walls as shielding (MU metal).
•
Do not plug or remove the devices during operation!
•
Before removing a router, also remove the relevant plugs and
connectors.
