Operating Conditions:

• Ambient air temperature should not exceed +40°C and should not be lower than -5°C, with a 24-hour average temperature not exceeding +35°C.
• The surrounding air should be clean, with relative humidity not exceeding 50% at a maximum temperature of +40°C. Higher relative humidity is allowed at lower temperatures, such as 90% at +25°C, which may occasionally cause moderate condensation.
• Designed for indoor use, with an altitude not exceeding 2000 meters.
• Should be installed in locations free from significant shaking, impact, or vibration.
• Pollution level: Grade 3.
• Seismic intensity: 8 degrees.
• During transportation and storage, the switchgear temperature can range from -25°C to +55°C, and it may reach up to +70°C for short periods (no more than 24 hours).
• If these operating conditions cannot be met, the user and manufacturer should negotiate a solution.
