2. Installation2.1 Prerequisites for the location of useCAUTIONUV LIGHTPlastics will become brittle when exposed to UV light. This artificialaging will reduce the easyE4 unit's lifespan. Protect the device from dir-ect sunlight and other sources of UV radiation.The environmental ambient conditions for operation must not exceed the specified val-ues:Ambient climatic conditionsAir pressure (in operation) 795 - 1080 hPamax. 2000 m NHNTemperatureOperation - 25 – +55 °C (-13 – +131 °F)The display is readable between ϑ -5°C (-23°F) ≦ T ≦ 50°C (122°F).Storage / Transport - 40 – +70 °C (-40 – +158 °F)Humidity Relative humidity 5 - 95 %Condensation Prevent condensation by means of suitable measures2.1.1.2 Aeration and de-aerationl The device uses natural convection-based passive cooling, i.e., it does not use fans.l Make sure that there will be enough volume for air changes inside the control panel,etc.The specified clearance around the easyE4 is: a, b, c ≧ 30 mm (1.2")l When installing the easyE4 in complex systems together with other assemblies,you must ensure that there will be enough air circulation in order to prevent over-heating.Ambient temperature for natural convection for devices with a display: ϑ -25°C (-13°F) ≦ T ≦ 55°C (131°F)The display will be readable between ϑ -5°C (-23°F) ≦ T ≦ 50°C (122°F).The panel builder is responsible for the temperature rise calculation. Eaton willprovide heat dissipation data for the easyE4 as necessary for design verification inaccordance with IEC EN 61439.easyE4 11/18 MN050009 EN www.eaton.com 39
