3.2.14 PSUI

Introduction

Each cabinet in Hicom 150 E OfficePro requires one PSUI power supply module. A cumulative LED indicates the presence of all the necessary secondary voltages. When a PSUI fails, it must be replaced. Do not attempt to replace individual fuses within the PSUI. Service technicians should not open or repair the board.

The PSUI is used in the OfficePro models for every country. The ring frequency and ring voltage of the integrated ring generator can be adjusted country-specifically.

For production reasons, two different PSUI units with the same function exist. The two PSUI units are interchangeable and differ only in the location of the ring-current switch.

UPSM and PSUI cannot both be used in the same system.
