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.
