The radio tray is available for fitting the customer 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.
At the customer request, and subject to additional fees, Siemens may customise 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 a Siemens Sales representative to discuss these services.
Optionally the Radio Tray can be fitted with a Operator Control Panel on the reverse side as shown
below. The Operator Control Panel is an accessory to the RCU. An Operator Control Panel fitted to
an RCU provides a local operator with the ability to send trip, close and protection controls and view
of the current state of the switchgear connected to the RCU by short range radio.
The Operator Control Panel is fitted inside the RCU enclosure and can be accessed by the operator
when the RCU door is open.
