2. Installation
2.1 Prerequisites for the location of use
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 dir-
ect sunlight and other sources of UV radiation.
The environmental ambient conditions for operation must not exceed the specified val-
ues:
Ambient climatic conditions
Air pressure (in operation) 795 - 1080 hPa
max. 2000 m NHN
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 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 will
provide heat dissipation data for the easyE4 as necessary for design verification in
accordance with IEC EN 61439.
