3.4.4 Environmental Conditions
The equipment operates properly within the following environmental limits if it has been cor-
rectly mounted according to the above mentioned recommendations:
Operating Temperature -25°C to +70°C
Relative Humidity 10 to 95% non-condensing
Operating Altitude Up to maximum 2000m
Storage Temperature -40°C to +70°C
Storage Humidity 10 to 95% non-condensing
Storage Altitude Up to maximum 3000m
In any other mounting position than the one explained above, the specified
operating temperature has to be derated to -25°C to +40°C.
3.4.5 Earthing
Earthing the eWON is necessary to eliminate unwanted transients and to conform to the EMC
requirements. Therefore, a functional earth (FE) terminal is available on the main connector as
shown in Specification of the External Power Supply, p. 22.
Connect this terminal directly to allow impedance ground. Shielded cables have to be used for
Ethernet and USB to comply with the EMC requirements.
3.5 Battery
The eWON Cosy 131 contains a CR2032 battery. This battery is used to maintain the real time
clock up-to-date even when the unit is not powered.
Risk of explosion if the battery is replaced by an incorrect type. The battery is not
intended to be replaced by the consumer: the product shall be returned to the
manufacturer for replacement.
