3.2.17 UPSM

Introduction

Each cabinet in Hicom 150 E OfficePro requires one UPSM (uninterruptible power supply modular). This board integrates the power supply and battery management functions. No other components are required if operated on a network.

To maintain short-term battery emergency operation after a power failure, that is, to use uninterruptible power supply functions, you must also connect one of the following to the UPSM:

One battery pack per system cabinet
One battery cabinet (BSG 48/38), including battery charger, or
One 48 Vdc network

 
Each connection must have a ferrite bead provided between the UPSM and battery pack, battery cabinet or 48 V dc network. Insert the ferrite bead (Würth 742 7113 or C39022-Z7000-C7) with two windings into the connecting cable at the UPSM output.  

UPSM and PSUI must not be used together in one and the same system.

For production-related reasons there are two different UPSM models. Technically identical, the two models have minor mechanical differences and are fully compatible with each other.
 
The UPSM necessitates a modification to the sheet-metal rear of the cabinet. The UPSM can be installed in the following cabinets: 
Basic cabinet
Expansion cabinet 1: S30777-U706-X, status 10 and later
Expansion cabinet 2: S30777-U706-X100, status 2 and later 
For U.S. only:  
The UPSM can be installed in the following cabinets: 
Basic cabinet
Expansion cabinet 1: S30777-U709-X
Expansion cabinet 2: S30777-U709-X100
The UPSM can also be installed on new backplanes with re-oriented Champ connectors. The battery back-up function of the UPSM is not used in the U.S. 

An LED lights up to indicate that the UPSM is in operation. The UPSM must be replaced when defective (LED does not light up).
The UPSM is used in models for all countries. The ring frequency of the modular ring generator can be parameterized to suit requirements.
 
Caution 
When mounting the UPSM on the cabinet frame, be careful to prevent screws from falling into the power supply unit through the ring generator opening. If a screw falls inside the UPSM, remove the screw before starting up the unit.

BSG 48/38

You can use a BSG 48/38 battery cabinet in an upright housing instead of the battery pack or a 48 V direct current supply to extend the bridging time in the event of a power failure. The BSG 48/38 battery cabinet (S30122-X5950-F300) consists of

an upright housing
a charging rectifier
a 38 Ah/48 V battery set

The battery cabinet is designed for direct connection to the Hicom 150 E OfficePro communication system. The DC power cable (S30122-X5950-F310) provided lets you connect any UPSM to the battery cabinet (do not connect to extension cables).
 
For detailed information about safety precautions as well as using and connecting the battery cabinet, refer to the installation and startup instructions that came with the cabinet.
