Cabling Rules
Shielded cables must be used for Ethernet and USB connectivity to comply with the EMC
requirements.
USB cable must be:
•
Shorter than 3m
•
USB 2.0 type A (on Ewon Cosy+ side)
•
Minimum current per contact : 0.5A (or better)
Caution
To prevent accidentally pulling out wires, be sure that cables are firmly attached to wire
connectors. For screw connectors, make sure that screws are properly tightened as well
as routing the equipment wires separately from other high voltage wires.
3.4.6
Environmental Conditions
The equipment operates properly within the following environmental limits if it has been
correctly mounted according to the above mentioned recommendations:
Operating Temperature
-25°C to +60°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.
3.4.7
Earthing
Earthing the Cosy+ 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. 20
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
Internal Battery
The Ewon 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.
Here is a list of risks and recommendations regarding the battery:
•
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.
•
Do not ingest battery, chemical burn hazard.
