3. Safety, Environmental and Regulatory Information
3.1. Scope
The present secon addresses safety, environmental and regulatory informaon for the Ewon® Flexy 205.
This safety, environmental and regulatory informaon generally has a similar compliance frame but some aspects
dier. For example: in the case of telecommunicaon extension cards, addional direcves, standards and
instrucons apply.
3.2. Power Supply
The external power supply is a third party device that is not part of this cercaon. The device shall be powered
by an LPS power supply cered according to its more recent UL/ IEC standards or Class2 per NEC or by a
12-24Vdc 100w max. cered for 60°C and for altudes up to 2000m for conformity to ts more recent UL/IEC
standards.
For more informaon, check the Cercaons secon of our website or refer to
Specicaon of the External Power Supply (page 30).
3.3. ESD Damage Prevention
To avoid possible damage to the base unit and / or extension card, please wait 30 seconds aer switching o the
equipment before inserng (or removing) an extension card.
IMPORTANT
Always use ESD precauons when handling extension cards and / or opened base unit as they
contain parts and assemblies suscepble to be damaged by electrostac discharge (ESD).
The printed circuit boards (PCBs) of the Ewon® Flexy 205 described in the present document are parally exposed
when slot llers are removed to place extension cards. In order to avoid ESD damage, the product, when it is
opened, must be handled with the necessary precauon including:
• Grounded ESD funconal work surface
• Personal grounding
•Vericaon that the conguraon is compable with the rmware capabilies before being operated.
The extension cards described in this document are modules exposing both sides of an electronic printed circuit
board.
Therefore, they are packed in an stac ESD bags. In order to avoid ESD damage, the product must be handled
with the necessary precauon as described above.

3.7. Internal Battery
The Ewon® Flexy 205 contains a CR2032 baery. This baery is used to maintain the real me clock up-to-date
even when the unit is not powered.
Here is a list of risks and recommendaons regarding the baery:
• Risk of explosion if the baery is replaced by an incorrect type. The baery is not intended to be replaced by
the consumer: the product shall be returned to the manufacturer for replacement.
• Do not ingest baery, chemical burn hazard.
• Keep new and used baeries away from children.
• If the cell baery is swallowed, it can cause several internal burns in just 2 hours and can lead to death.
• If the equipment’s enclosure do not close securely, stop using the product and keep it away from children.
• If you think baeries might have been swallowed or placed inside any part of the body, seek immediate
medical aenon.
IMPORTANT
Risk of explosion if the baery is replaced by an incorrect type. The baery is not intended to be
replaced by the consumer: the product shall be returned to the manufacturer for replacement.

requirements. Therefore, a funconal earth (FE) terminal is available on the main connector as shown in
Specicaon of the External Power Supply (page 30).
Connect this terminal directly to allow impedance ground. Shielded cables have to be used for Ethernet and USB
to comply with the EMC requirements.
3.8.4. Environmental Limits
The equipment will operate properly within the following environmental limits provided it is mounted according
to Mounng Recommendaons (page 6).
Characteristic Value
Operang temperature -25° to +60°C
Storage temperature -40° to +70°C
Relave humidity 10 to 95% non-condensing
Operang altude Up to maximum 2000m
Storage altude Up to maximum 3000m
Mounng Latch for DIN rail EN50022-compliant
3.8.5. Labelling Information
The OEM User Manual (for integrators) must provide clear instrucons, to the OEM, explaining the labeling
requirements, opons and OEM User Manual instrucons that are required.
The host OEM User Manuel (Ewon's manual) must contain clear instrucons on how end users can nd and/or
access the module and the FCC ID.

4.2. Mechanical Dimensions
Figure 2. Mechanical Dimensions
In the above picture:
•Unit: Dimensions are in millimeters (mm).
•Accuracy: Suited only for implementaon drawings (rounded @ full mm).
Shaded areas show provisions of empty space that should be considered in the implementaon arrangement.
The provision of empty space in front of the slot llers is spared for the connectors of extension cards. Even if the
applicaon requires no extension card(s), it is good pracce to plan the free space anyhow, in case an extension
card is inserted later on.
