50°C, or the humidity is lower than 10% RH / higher than 90% RH
b. Use in locations where the temperature is lower than 0°C / higher than 40°C, or
the humidity is lower than 25% RH / higher than 85% RH
c. Sealed places such as a cabinet without gaps, places where a flammable gas or
corrosive gas is present, places with saline content or water droplets, places that
