The radio tray is available for fitting the
user-specific radio, modem or other means
to connect to the utility’s SCADA system.
It is the responsibility of the user to correctly
configure the RCU with the selected
communications means and to verify the SCADA
controls and events perform as expected.
On request, and subject to additional fees,
Siemens may customize the radio tray to
meet a specific communications device
mounting. Further, Siemens may also
provide a value-added service by fitting and
testing the communications device in the
factory prior to shipment. Please contact
Siemens to discuss these services.
