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.
CAUTION
SHORT-CIRCUIT HAZARD
If the device is or has been exposed to environmental fluctuations
(ambient temperature, air humidity), condensation may form on or
inside it. As long as this condensation is present, there will be a short-
circuit hazard.
Do not switch on the device when it has condensation in or on it.
If the device has condensation in or on it, or if the panel has been
exposed to environmental fluctuations, let the panel settle into the
existing ambient temperature before switching it on. Do not expose the
device to direct thermal radiation from heating appliances.
The ambient conditions must be met when transporting and storing the easyE4.
The ambient air temperature for storage and transportation must not exceed the max-
imum specified limit:
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
Before commissioning
If storing/transporting the device in cold weather conditions or in
such a way that it will be exposed to extreme differences in tem-
perature, make sure that no condensation forms on or inside the
device.
If there is condensation in or on the device, do not switch on the
device until it is completely dry.
