Snap the device onto an IEC/EN60715 DIN-rail.The DIN-rail must establish a conductive connection to the control panel'sback plate. The device must be installed in a horizontal position (device desig-nation on top).In order to ensure that the maximum operating ambient temperature will notbe exceeded, make sure that there is enough clearance between the systemblock's vents and any neighboring components, as well as between thevents and the control panel's back plate.Figure 10: Horizontal installation only!2.4.2 Mounting the system block on the DIN-railBefore mounting the device, make sure that you have configured thedevice's field bus address and, if necessary, that the bus termination resistor(if any) has been activated with the corresponding DIP switch.To mount the system on the DIN-rail, join the XN 300 slice modules and thegateway to form a system block and then snap the entire system block ontothe DIN-rail.To mount the system block, follow the steps below:a b c ϑ30 mm (1.18“) 30 mm (1.18“) 100 mm (3.94“) ≦ 55 °C (≦ 131 °F)aabbc
