Operating Conditions and Environmental Suitability:
●Ambient temperature is -5℃~+40°C, the average temperature during 24 hours couldn't exceed +35°C.
●Altitude: ≤2000m.
●Atmosphere condition:
1.Humidity: Relative humidity of the atmosphere couldn't exceed 50% when the highest temperature is +40°C; much higher relative humidity is allowable under the condition of lower temperature, for example, when the temperature reaches +20°C, the relative humidity is up to 90%, taking into account the condensation that may occur on the product surfaces due to temperature changes.
2.Pollution grade: 3.
●Installation condition:
1.The HZ10 series combination switch should be installed in an environment without significant shaking, impact, vibration, and without exposure to rain or snow.
2.It should be installed in an environment without the risk of explosion or substances that could corrode metals and damage insulation (including conductive dust).
3.Installation category: III.
