The control cabinet heater, for DIN rail mounting, reliably prevents the formation of condensation, corrosion and leakage currents caused by condensation. Maximum efficiency is achieved when the control cabinet heater is installed vertically, with the cable entry pointing downwards. The control cabinet heater should be installed below the system to be protected, as heated air rises. Non-binding rule of thumb: 1 watt per 10 liters of free space.
