Line Power Module Installation

Figure 9-4: SN1400 External 40V Power Supply
Warning:
Do not connect more than one phantom power supply on the BRI ports. Since line power is
connected between BRI port 0 and 1, the power supplies may be damaged even if they are on
separate ports.
Note:
The BRI Port that has no external PSU connected is supplied with power internally through the
SmartNode, from the BRI port that has the external PSU connected.
Warning:
For this installation option do not use any other phantom power supply than the PM-BRI-
ext supplied by Inalp Networks AG. The PM-BRI-ext power supply unit is equipped with a
transformer that is specially designed for S-Bus line power. The use of a general purpose DC power
transformer may cause equipment damage.
Note:
The appearance of the three-way multi-connector may differ from the one depicted, depending
on the vendor that you have chosen.
