12.9. External units
12.9.1. PR030/B
PR030/B is an external unit that allows the relay to be powered in order to perform installation, Autotest and Trip
Test, and the verifi cations with the CB open. The unit is connected to the relay by means of the front connector.
12.9.2. PR010/T
The SACE PR010/T unit allows the parameters and log data recorded by the relay to be checked.
It also allows threshold operation to be checked as well as the tripping times of the L-S-I-G protection functions.
The unit is supplied in a case containing the connection cables, external power supplier and rechargeable
batteries, cable and SW for PC.
The SW in the PC allows several fi les corresponding to the devices with which it is possible to interface, to
be loaded into PR010/T. It also allows test reports to be downloaded. Thus the corresponding fi le must be
loaded into the PR010/T unit before it can be used with relay PR121.
The unit is connected to the relay by means of the front connector using a dedicated cable.
Consult the Operation Manual of the unit (RH0025) for further details.
12.9.3. BT030-USB
Using the BT030-USB unit, PR121/P can communicate with a PC via wireless link or USB fl ash drive, thereby
extending the range of information available to the user.
Communication is enabled via Ekip Connect SW, the installation package of which is in the BT030-USB set.
This set also includes the USB cable and batteries for use in the wireless confi guration.
The unit is connected to the relay by means of the front connector.
12.9.4. EKIP T&P
The Ekip T&P unit allows relay powering, communication and testing via a PC by means of a USB adapter.
Similarly to BT030-USB, communication is enabled via Ekip Connect SW, the installation package of which is in the Ekip T&P
set. The set includes the USB module and a series of adapters for various types of relay.
WARNING: Ekip T&P must be used for PR121/P with USB module and a dedicated cable for PR121/P (the picture
below is for explanatory purposes only). Consult the Ekip Connect SW Operation Manual (1SDH000891R0001)
for further details.
12.9.5. HMI030
PR121/P can also be connected to the HMI030 switchgear front external unit so as to display the
current values measured.
HMI030 connects to the connector on the rear side, on the relay, whose external connection is
provided by the contacts on the terminal box in the CB.
Auxiliary power supply for the relay and HMI030 is not required for this function.
