INSTALLATION

Operating temperature: -25 to +55°C (-13 to +131°F)
(-5 to +40°C or 23 to 104°F, 30 to 80 % RH non-condensing, for EU conformity.)
Operating humidity: 30 to 90 % RH (non-condensing)
(-5 to +40°C or 23 to 104°F, 30 to 80 % RH non-condensing, for EU conformity.)
Mounting: DIN Rail (TH35-7.5, 1-mm-thick)
Oxide film on the surface of an aluminium DIN rail may lower the electric conductivity between this module and the ground. Use a steel or copper rail.
