Normal service conditionsNormal service conditions
● Ambient temperature: upper limit +40°C, lower limit -15°C (with special technology, it can reach -45°C);● The altitude does not exceed 2500m (with special technology, it can reach 4000m);
● The relative humidity of the surrounding air should not exceed 50% when the maximum temperature is +40°C. A larger relative humidity is allowed at lower temperatures, such as 90% at +20°C. It should be considered that changes in temperature may The effect of accidental condensation;
● When the device is installed, the inclination with the vertical plane does not exceed 5°, and the entire cabinet row is relatively flat (in compliance with GBJ232-82 standards);
● The device should be installed in a place where there is no severe vibration and impact and where the electrical components are not subject to undue corrosion;Technical parameter

Structure and Dimensions
The GCS series switch cabinet is installed vertically, not against the wall. Behind it is the outlet cable trench of the cabinet. To facilitate maintenance, the distance from the back to the wall is usually 800~1800mm: see the figure below for the front distance installation.
