SCS 104
4 Installation and connection
4.1 Installation site requirements
The unit mounts in a 19 inch rack. Due to the weight the housing requires rails. These are available from the cabinet/rack manu-
facturer.
Please note, cooling generates waste heat inside the SCS. Adequate ventilation is therefore required (e.g. fan slot inside the cab-
inet).
The following requirements must be met during installation:
– Never install the system near sources of heat or vibration, in direct sunlight, or around high frequencies or magnetic fields.
The operator must install a lightning arrester.
– The system must be permanently installed in a location which can support the weight of the system.
– It must be protected from shock and impact.
– Never expose the display components to external forces.
– Never install the system outdoors.
4.2 Gas Line Connections
DANGER Toxic, acidic gasses
Sample gas can be harmful.
a) The gas lines and electric cables must be connected by a professional. Observe local
laws and regulations.
b) If necessary, ensure a safe gas discharge.
c) Switch off the gas supply before performing maintenance and secure against acci-
dental opening.
d) Protect yourself from toxic/corrosive gases. Wear suitable protective equipment.
The gas connections are 1/4” bulkhead fittings. Ensure the connections are tight.
