Mounting The Device; Mounting The Device On A Din Rail - Siemens SIMATIC NET RUGGEDCOM RS900G Equipment Manual

RUGGEDCOM products include transient suppression circuitry to protect against
damage from electrical transients and conform with IEC 61850-3 and IEEE 1613 Class
1 standards. This means that during a transient electrical event, communications
errors or interruptions may occur, but recovery is automatic.
Siemens also does not recommend using copper Ethernet ports to interface with
devices in the field across distances that could produce high levels of ground
potential rise (i.e. greater than 2500 V), during line-to-ground fault conditions.

Mounting the Device

The RUGGEDCOM RS900G is designed for maximum mounting and display flexibility.
It can be equipped with adapters that allow it to be attached to a DIN rail or panel.
Heat generated by the device is channeled outwards from the enclosure. As such, it
is recommended that 2.5 cm (1 in) of space be maintained on all open sides of the
device to allow for some convectional airflow.
Forced airflow is not required. However, any increase in airflow will result in a
reduction of ambient temperature and improve the long-term reliability of all
equipment mounted in the rack space.
Note
For detailed dimensions of the device with either DIN rail or panel hardware installed,
refer to "Dimension Drawings" (Page 23).

Mounting the Device on a DIN Rail

For DIN rail installations, the RUGGEDCOM RS900G can be ordered with a DIN rail
adapter preinstalled on the back of the chassis. Use the adapter to mount the device
to a standard 35 mm (1.4 in) IEC/EN 60715 or TS35 DIN rail.
Mounting the Device
To mount the device to a DIN rail, do the following:
