2. Installation
2.1 Prerequisites for the location of use
2.1.1.1 Temperatures
Make sure that the device does not overheat.
Do not expose the device to direct sunlight or other sources of heat.
The minimum clearance to components that radiate heat, such as transformers
under heavy loads, is 15 cm.
CAUTION
UV LIGHT
Plastics will become brittle when exposed to UV light. This artificial
aging will reduce the easyE4 unit's lifespan. Protect the device from
direct sunlight and other sources of UV radiation.
The environmental ambient conditions for operation must not exceed the specified
values:
Ambient climatic conditions
Air pressure (in operation)
795 - 1080 hPa
Max. 2000 m above sea level
Temperature

Operation
- 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 measures
2.1.1.2 Aeration and de-aeration
l
The device uses natural convection-based passive cooling, i.e., it does not use
fans.
l
Provide sufficient volume for the exchange of air in the switch cabinet etc.
The specified free space around the easyE4 measures: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: ϑ -25°C (-13°F) ≦ T ≦ 55°C (131°F)
The display (option) 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 will
provide heat dissipation data for the easyE4 as necessary for design verification
in accordance with IEC EN 61439.
