Differences in indoor and outdoor use of complete equipment

 The differences between indoor and outdoor use of complete equipment sets primarily lie in the level of protection, environmental adaptability, and functional design. It is necessary to tailor the installation conditions and usage requirements according to the specific equipment type (industrial control, power facilities, or outdoor living equipment).

Industrial control equipment: Protection level and installation specifications

Basic protection requirements

Industrial complete control equipment (such as PLC systems) requires a clear protection level based on the installation location:

• Indoor environment: The protection level should not be lower than IP21 (protection against solid foreign objects ≥12.5mm, protection against vertical dripping water).
• Outdoor environment: It must meet IP54 or above standards (dust-proof, splash-proof), and the cabinet body must adopt anti-corrosion spray painting process. Outdoor remote I/O cabinets also need to be designed with anti-condensation heaters and other features.

Adaptation to special environments

• Explosion-proof scenario: In outdoor flammable and explosive environments, flameproof enclosures or positive pressure explosion-proof cabinets are required.
• Seismic design: The equipment must withstand an earthquake intensity of magnitude 8, and the cable routing strictly separates power lines from signal lines (with a spacing >20cm).

Power facilities: case of outdoor dedicated equipment

• Grounding Resistance Cabinet: It is divided into indoor and outdoor models. The outdoor model is equipped with wall bushing and lifting rings, supports extreme temperatures ranging from -40℃ to 55℃, has a protection level of IP55, and can be equipped with an intelligent monitoring module for real-time feedback of operational data.
• Redundant configuration: The PLC of critical power equipment (such as transformer neutral point control system) requires redundant design to ensure automatic switching to a safe state in case of failure.

Key precautions

• Industrial equipment: It is required to pass Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), and undergo regular inspections of the grounding system and module status during the operation and maintenance phase.
