-48 Vdc
(-72 to -36 Vdc)
This connector is mounted on TPRN back panel.
A fuse is provided underneath the –48 Vdc
connector, and has to be replaced in case it
fails (when it happens the supervision system
detects the failure).

Whatever power supply is chosen (85 to 264 Vac or -72 to -
36 Vdc) an additional external ground terminal is provided
on the TPRN rear (fig. 5.5).
The external power supply (220Vac or -48Vdc) is converted into a +12Vdc
voltage allowing feeding the active modules inserted into the TPRN.

TPRN ports
The TPRN sub-rack is provided with a set of I/0 ports which allows the
connection to any external device.
connection to any external device.
RS232 serial port
The RS232 serial port can be used to connect the TPRN sub-rack to the
remote supervision unit or to a laptop running LMT software. Please note that
a standard RS232 cable is needed.
The connection baud rate can be set to 9600bps or 19200bps, by properly
remote supervision unit or to a laptop running LMT software. Please note that
a standard RS232 cable is needed.
The connection baud rate can be set to 9600bps or 19200bps, by properly
setting the dip-switch 5 standing on the interior TPRN backplane (fig. 5.6).
The baud rate setting through dip-switch 5 is shown in table 5.1.
The baud rate setting through dip-switch 5 is shown in table 5.1.
