7 SW1 Connection of the service com-
puter (local)
RJ45
8 SW2 Connection of service computer
(local) ‒ optional for controller
redundancy
This connection is required only if
software downloads should be
performed specifically for the
redundant BSCU.

3.2.1.3 GNSS splitter
The GNSS splitter (Global Navigation Satellite System) is used for connecting the GNSS
antenna and the splitting and distribution of the received GNSS signal (e.g. GPS, Galileo
or Glonass) to two BSCUs. The GNSS splitter is always installed in the connection and
control panel, even if only one BSCU is used.

V
AC
voltage supply
The DIB-R5 advanced can be operated with an input voltage of 90 V
AC
to 250 V
AC
.
The V
AC
voltage supply consists of the following components:
n
Ä
AC Power Distribution Module (APDM)
n
Ä
Power Supply Unit (PSU) including Power Supply Module (PSM)
3.2.2.1 AC Power Distribution Module (APDM)
The AC Power Distribution Module (APDM) is used for connecting the voltage supply and
the voltage distribution to the backplane and the installed hardware components. The
APDM is used for the V
AC
voltage supply. The V
AC
input voltage is fed via the Power
Supply Unit (PSU), converted to the required operating voltage, and subsequently distrib-
uted to the backplane and the installed hardware components.
With redundant voltage supply feed, two APDMs are installed (optional). The redundancy
options of the voltage supply are described in
Ä
Chapter 3.5.6 “Redundant V
AC
voltage
supply” on page 62.
The following figure shows the top view of the APDM. The following table describes it in
detail.
