Application Guide:

Ambient Temperature:

Normal operating conditions: Maximum ambient temperature not exceeding 40°C; 24-hour average temperature not exceeding 35°C, and the average value measured within the year is lower than this; minimum ambient temperature not below -5°C.

Allowable operating conditions: -40°C to 85°C.

Altitude:

Normal operating conditions: Installation altitude not exceeding 2000m.

Allowable operating conditions: 2000m to 4500m.

Atmospheric Conditions:

Normal operating conditions: Clean air, relative humidity does not exceed 50% at 40°C; higher humidity is allowed at lower temperatures; under these conditions, moderate condensation may occur occasionally due to temperature changes.
