Division 2 area.
The FLA3301_00H has the same features as the FLA 3301 - 2 Serial Ports extension card (FLA3301_00) except it
received ocial cercaon to be placed and used in a Class 1 Division 2 area.
This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D OR non-hazardous locaons only.
WARNING
EXPLOSION HAZARD: Do not disconnect while the circuit is live or unless the area is free of ignitable
concentraons.
To ensure a proper venlaon of the equipment, a free gap of at least 2 cm must be respected in front of all
upper and lower venlaon openings of the unit. A free gap of at least 1 cm must be respected on each side of
the unit.

4.7.1. Base Unit Slot Compability
The FLA 3301 - 2 Serial Ports extension card must be inserted in one of the “A” slots of the base unit.
The reference code of the extension cards includes a leer dening their compability:
• FLA xxxx: designate cards that t into “A” slots.
In addion to the card reference, each type of extension card bears a visual compability symbol on its front
panel:
Design Slot Type Flexy 205 Locaon Flexy 10x & 20x
●●○○ A Any slot 2 rst slots only
Ewon Flexy 205:
As the Flexy 205 has room for 2 slots, the type slot compability rule doesn’t apply. The FLA 3301 - 2 Serial Ports
extension card can be inserted in both slots.

Ewon Flexy 10x & 20x:
The FLA 3301 - 2 Serial Ports extension card must be inserted in the “A” slots which are the two slots on the far
le of the Flexy 10x & 20x.
Figure 5. Posion of the “A” Slots on a Flexy 10x & 20x.
WARNING
Cards that t only in one slot type have a mechanical mistake-proof security to prevent them from
being inserted in an incorrect slot type.
4.7.2. How to Insert into the Flexy Base Unit
Wait 30 seconds aer turning o the equipment before inserng (or removing) an extension card to avoid
possible damage to the base unit and the extension cards.
Remove the slot ller of the locaon the new card will be inserted. To do so, press on both ends of the cover,
note that the hooks are o-centered.

1Hooks to be pressed are o-centered. Press while pulling upwards
2This metal tag soldered on the PCB acts as mistake-proof security (mang stop in housing). Doesn’t apply on Flexy 205.
Insert the extension card carefully and slide it down unl the hook clicks. Make sure the card is completely
inserted.
CAUTION
DO NOT insist if a resistance is felt when trying to insert the card.
This can occur if the extension card is inserted in a wrong slot type. In such case, check slot
compability of the relevant extension card.
If an extension card is inadvertently forced in a wrong slot, the base unit will detect the misplaced
card and will not complete its boot process. Therefore, the unit will not be accessible through its LAN
interface. The slot error is returned by the USR LED. (red ON 1 sec, OFF 0.5 sec).
Boot the unit for the inserted extension cards to be detected. The web interface of the Flexy base unit has a
diagnosc page showing the extension cards in their order of detecon (from le to right).
4.7.3. Inseron of Mulple FLA 3301 - 2 Serial Ports extension card
Detecon Order
The boot sequence of the base unit includes an automated detecon of the inserted extension cards.
This detecon is done sequenally, slot per slot starng from le to right (when holding the base unit with its
logo on the right side).

Soware Compability
The base unit allows the inseron of mulple extension cards, somemes of the same type. Some conguraons
including mulple extension cards, even if mechanically acceptable, are not supported by the embedded
soware.
Cards in excess are ignored during the automated detecon process which means that the base unit and its
running extension cards will operate normally.
The Flexy rmware currently supports up to 2 FLA 3301 - 2 Serial Ports extension card.
The ignored card(s) will appear in the Diagnosc > Status > System Info > System but they will not be funconal.

Figure 7. Order of the Extension Cards
The picture above shows an example of a conguraon that would be OK mechanically and power wise but
would not be supported by the rmware.
During the boot process, the rst 2 serial port extension cards are detected and both can be used.
In case of 2 single Ethernet cards, these 2 cards are also detected but the second Ethernet card is not supported
by the rmware and cannot be used. The presence of this “ignored” card in the base unit does not alter the
operaon of the base unit itself nor does it alter its “accepted” extension cards.

4.8. Firmware Port Naming Convenon
Depending on the Base Unit and applying the le to right detecon order of the extension cards, following port
naming (COM1, COM2, ...) will be applied inside the Ewon rmware.
