General safety notices relating to protection against explosion
WARNING
EXPLOSION HAZARD
Safety notices when using the device according to Hazardous Locations (HazLoc)
Note the following safety notices. These relate to the entire working life of the device.
You should also read the safety notices relating to handling in the individual sections,
particularly in the sections "Installation" and "Connecting up".
DO NOT OPEN WHEN ENERGIZED.
If you use the device under HazLoc conditions you must also keep to the following safety
notices in addition to the general safety notices for protection against explosion:
This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or nonhazardous locations only.
This equipment is suitable for use in Class I, Zone 2, Group IIC or non-hazardous locations
only.
With the optical bypass relay SCALANCE XC100-4OBR, you can activate and deactivate
end devices in bus, star and ring structures without interrupting the communication between
other network components.
If an error occurs, the bypass relay bypasses the connected end device so that the
connection in the network is retained.
An end device is a device connected to the network via a bypass relay.
When the SCALANCE XC100-4OBR is supplied with power, the network interfaces are
connected to the end device interfaces of the bypass relay
bypass relay is connected is therefore in the network.
If the voltage of the end device drops, for example due to a fault or during maintenance, the
voltage of the SCALANCE XC100-4OBR also drops. The monitoring voltage is no longer in
the set range.
The bypass relay then interconnects its two network interfaces within 10 ms. As result, the
connection to the end device that has been turned off is inactive and the bypass relay forms
the connection to the neighboring network components or bypass relays
②.
When you turn on the voltage of the end device and therefore of the SCALANCE XC1004OBR again, the two network interfaces remain connected until the end device is
operational. It is only after this startup time that the bypass relay connects the network
interfaces to the end device interfaces again.
The insertion loss is lower with a bypass relay without TAP functi
3.2 Purpose
In bypass mode, a SCALANCE XC100-4OBR with TAP function forwards the received data
not only to the neighboring network components. The TAP function has the effect that the
data is also sent to the end device. The end device receives and sends data as if it were
connected to the network. The data that the end device sends in bypass mode is not
forwarded to the network by the bypass relay.
With a bypass relay with TAP function, the end device can establish a link to the neighboring
network components in bypass mode.
If you use a bypass relay with TAP function in MRP or HRP rings, you can activate and
deactivate the connected end device without the redundancy manager initiating
reconfiguration routines in the ring.
If you use a bypass relay without TAP function in MRP and HRP rings, the redundancy
manager reacts when the connected end device is turned on or off again. The redundancy
manager enables the alternative (redundant) ring section and initiates the reconfiguration of
the logical communications connections.

3.3 Installation guidelines
Note the information on the topic of redundancy in the configuration manuals of the
connected devices.
You will find the configuration manuals of the SCALANCE X switches on the Internet pages
of Siemens Industry Online Support
If you want to bypass an (R)STP bridge with a SCALANCE XC100-4OBR using the TAP
function, connect the (R)STP bridge to the (R)STP network only via the two ports of the
bypass relay.
If the root bridge of an (R)STP network is bypassed by a bypass relay, an alternative root
bridge is selected. By turning the root bridge on and off, the (R)STP network is recalculated.
If an (R)STP bridge is bypassed, the (R)STP section is longer and attenuation increases.
This changes the path costs.
Within an MRP or HRP ring, a permanently configured redundancy manager must not be
bypassed using a bypass relay.
ails.
If the ring nodes are operated in the redundancy modes "MRP Auto Manager" or "Automatic
Redundancy Detection", any ring nodes can be connected and disconnected by the bypass
relay.
If the current redundancy manager is bypassed, another ring node takes over control of the
redundancy. If the redundancy manager changes, the logical communications connections
are reconfigured.
