2.3.6 Connecting the supply voltage
The supply voltage must be between 18 V DC and 30 V DC.
Supply the supply voltage to the module via the "24V" and "0V" terminal blocks or with the
system power supply unit via the DIN rail connectors (T-BUS).
You can supply other modules up to a maximum of 1.5 A via the device.
The terminal blocks for connecting the supply voltage, the switching outputs, and both DSL
ports are COMBICON plugs (plug-in screw terminal block). They can be removed and have
a keying profile that prevents plugs being mixed up.
Power can also be supplied via USB, but this is purely for configuration purposes. The
"VCC" LED flashes at 1 Hz in this case. DSL operation is not possible.
Connection to the module
Connect the 24 V supply voltage to the "24V" and "0V" terminal points.
As soon as the "VCC" LED lights up, the modem is ready to operate.
Figure 2-9 Connecting the supply voltage
Using the system power supply unit (optional)
Connect the MINI-SYS-PS 100-240AC/ 24DC/1.5 system power supply unit (Order No.
2866983) using two DIN rail connectors (Order No. 2709561) to the left of the PSI-MO-
DEM-SHDSL/SERIAL
(see "Mounting with DIN rail connectors (connection station)" on page 2-3).
As soon as the "VCC" LED is permanently on, the modem is ready to operate.
If the LED is off, no operating voltage is present. If it flashes at 1 Hz, the device is being
supplied via USB and if flashing at 2 Hz this indicates that an error occurred when boot-
ing.
WARNING: The PSI-MODEMSHDSL/SERIAL is designed exclusively for SELV opera-
tion according to IEC 60950/EN 60950/VDE 0805.
NOTE:
In order for the switching outputs (DO/DIO) to function, the modem must be supplied with
voltage via the COMBICON plug-in connectors. It is then not possible to supply the volt-
age supply via USB or the DIN rail connector.
The SHDSL modem has a limited temperature range. The temperature range depends on
whether the modem is supplied via COMBICON plugs or via DIN rail connectors (T-BUS).
