3.2.10 PSUI

Introduction
One PSUI power supply module is used for each cabinet in the Hicom 150 E OfficePro. Two different
PSUIs with the same function are used as a result of production processes. A cumulative LED
indicates the presence of all of the necessary secondary voltages. A PSUI must always be replaced if it
fails. A replacement of fuses within the device by a service technician is not permitted.
The PSUI is used in all national variants. The ring frequency and ring voltage of the integrated ring
generator can be adjusted as required (country-specific).
The two PSUIs are identical on a technical level but differ slightly on a mechanical level (position of
the ring current switch). The two PSUIs are fully compatible.
Part numbers of the two PSUIs
