Mounting
Preferred mounting position is horizontal (i.e. on a horizontal DIN rail which is
attached to a vertical wall). For all other mounting positions, a derating has to be
observed (see chapter 6).
Note:
The air vents have to be kept free with a sufficient spacing to other components, to
ensure optimal air ventilation.
The device is designed for easy snap in mounting on 35 mm x 7.5 mm
DIN EN 60715 rails (formerly DIN EN 50022).
Note:
The DIN rail should be attached to a mounting plate or an even back plane for best
stability.
Suitable fixtures, like end clamps or grounding terminals have to be used at both
ends of the station, to prevent sliding off the rail.
Note:
To ensure easy unlocking of the Ethernet connectors, use only clamps at the bus
controller side of the station that do not protrude more than 30 mm from the rail.
Note:
Only use clean and corrosion free mounting rails in order to ensure a safe contact
between the FE terminals.
