or device). However, it comprises important information that must be followed for personal safety, as well as
to avoid material damage. Information is highlighted and illustrated as follows according to the degree of
danger:
!
DANGER
DANGER means that death or severe injury will result if the measures specified are not taken.
²Comply with all instructions, in order to avoid death or severe injuries.
!
WARNING
WARNING means that death or severe injury may result if the measures specified are not taken.
²Comply with all instructions, in order to avoid death or severe injuries.
!
CAUTION

NOTE
Important information about the product, product handling or a certain section of the documentation
which must be given attention.
Qualified Electrical Engineering Personnel
Only qualified electrical engineering personnel may commission and operate the equipment (module, device)
described in this document. Qualified electrical engineering personnel in the sense of this manual are people
who can demonstrate technical qualifications as electrical technicians. These persons may commission,
isolate, ground and label devices, systems and circuits according to the standards of safety engineering.
Proper Use
The equipment (device, module) may be used only for such applications as set out in the catalogs and the
technical description, and only in combination with third-party equipment recommended and approved by
Siemens.
Problem-free and safe operation of the product depends on the following:
•Proper transport
•Proper storage, setup and installation
•Proper operation and maintenance
When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper
action is not taken, death, severe injury or property damage can result:
•The equipment must be grounded at the grounding terminal before any connections are made.
•All circuit components connected to the power supply may be subject to dangerous voltage.
•Hazardous voltages may be present in equipment even after the supply voltage has been disconnected
(capacitors can still be charged).
•Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting the
equipment, ensure that the current-transformer circuits are short-circuited.
•The limiting values stated in the document must not be exceeded. This must also be considered during
testing and commissioning.

The power relays operate in interlocked mode, that is, only one relay of each switching pair picks up at a time
thereby avoiding a power-supply short circuit.

NOTE
The firmware must be updated to version ≥ V7.90 if using the ETH-BD-2FO module. If the module is
connected to a device with a previous version, a hardware failure is reported that disappears with an FW
update to V7.90. As this is not an actual hardware failure, there is no need to send in the device.
The ETH-BD-2FO module offers the possibility of replacing the SFPs (Small Form-Factor Pluggable) delivered by
default for a communication route of up to 2 km by SFPs that can be ordered separately in order to adapt the
interface to different transmission media and longer routes.

Removing SFP Pluggable Transceivers
!
CAUTION
Risk of burns due to high temperatures of the SFP pluggable transceivers
Noncompliance with the safety notes may result in medium or light injuries.
²The SFP pluggable transceivers can be disconnected and plugged in while in operation. Siemens
recommends switching off the device.
²Allow the SFP pluggable transceiver to cool as much as possible.
✧ Remove the connecting cables or the dust protection cap that was plugged on in the delivery state from
the SFP pluggable transceiver.
✧ In order to release the interlocking, open the bracket on the SFP pluggable transceiver.
✧ Pull on the bracket in order to pull the SFP pluggable transceiver out of the slot. The removal must be
possible with free movement and without great exertion of force.
✧ Provide the SFP pluggable transceiver with the dust protection cap so that the optics are protected from
contamination.
Mounting SFP Pluggable Transceivers
✧Check whether the bracket on the SFP pluggable transceiver is closed.
The bracket must be closed.
✧ Insert the pluggable transceiver into the slot until it audibly locks in place.
The SFP is securely fixed in the slot.
i
i
NOTE
Check for secure positioning of the transceiver in the slot and whether it is locked in place in order to avoid
unintentional removal by pulling on the connection line.
