1. Ensure ambient air temperature remains within the safe range: not exceeding +40 °C, not dipping below -5 °C, and keeping an average temperature of no more than +35 °C over 24 hours;
2. Maintain relative humidity not exceeding 50% at the maximum +40 °C. A higher humidity level is permissible at lower temperatures, such as up to 90% at +20 °C;
3. Operate in a pristine air environment devoid of corrosive, explosive gases, and free from conductive and insulating dust;
4. Install vertically in stable conditions, with negligible shaking or vibrations. Inclination should not surpass 5 degrees;
5. Ensure installation at altitudes not exceeding 2000 meters;
6. For storage and transport, the temperature range should be between -25 °C to +55 °C, with short durations (under 24 hours) not exceeding +70 °C;
7. Should these conditions prove challenging, users are encouraged to engage in discussions with the manufacturer to find suitable solutions.
When placing an order, the User should provide the following:
1. A comprehensive main circuit distribution system diagram including phase layout, rated working voltage, current, protection device operating current, alongside necessary technical parameters.
2. Clearly state the specifications for incoming and outgoing cables.
3. Detail the model, specification, and quantity of the primary electrical components housed within the differential cabinet.
4. Specify if bus extrusion or bus ducting is needed between switch cabinets or incoming cabinets, detailing required data like span and elevation from the ground.
5. For switch cabinets used in special environmental conditions, outline these specifics clearly when ordering.
6. Specify the surface color of the switch cabinet along with any other particular requirements to ensure customization to your needs.
