Railway applications
The CloudGate LTE has successfully been tested according to EN 50155. This standard
applies to all electronic equipment installed on rail vehicles and associated with the
accumulator battery of the vehicle or a low voltage power supply.
Conditions of operation
This device is suited for railway applications under the following conditions:
altitude class AX (up to 2000m)
ambient temperature class T3 (-25°C to +70°C)
power supply: 24V DC
interruptions of voltage supply class S1 (no interruptions)
Installation
The supply to the CloudGate LTE should be provided by a separate conductor
connected as directly as possible to the source. This conductor should be used only for
the supply to electronic circuits.
The installation of the electronic equipment shall be arranged so as to reduce, as far as
possible, the effects of external electrical disturbances.
In order to offer sufficient electrical insulation, an external DC/DC convertor shall be
used. Minimum isolation provided shall be 500Vdc. During the EN 50155 testing this
DC/DC convertor was used for the insulation test.
