2.4.4. Environmental conditions
The equipment will operate properly within the following environmental limits if it has been
correctly mounted according to the above mentioned recommendations:
Operating T°
-25°C to +70°C
Relative Humidity
10 to 95% non-condensing
Operating altitude
Up to maximum 2000m
Storage temperature
-40 to +70 °C
Storage Humidity
10 to 95% non-condensing
Storage altitude
Up to maximum 3000m
2.4.5. Earthing
Earthing the eWON is necessary to eliminate unwanted transients (lightning protection) and
to conform to the EMC requirements. Therefore, a functional earth (FE) terminal is available
on the main connector as shown in
A.2. Specification of the External Power Supply
.
Connect this terminal directly to allow impedance ground. Shielded cables have to be used
for Ethernet and USB to comply with the EMC requirements.
2.5. Battery
The COSY contains a CR2032 battery. This battery is used to maintain the real time clock up-
to-date even when the unit is not powered.
- Caution -
Risk of explosion if 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.
