UPSM

Introduction
Each cabinet in HiPath 3750 and HiPath 3700 requires one UPSM (Uninterruptible Power Sup-
ply Modular). This board supports power supply and battery management functions. No other
components are required if operated as an AC power supply. To maintain short-term battery
emergency operation after a power failure, that is, to use uninterruptible power supply func-
tions, you must also connect a battery pack per system cabinet or a
(including battery charger) to the UPSM.
Warning

The UPSM power supply is only released for permanent AC power supply. Perma-
nent operation at a direct-current system is not allowed.
A DC power supply unit is only connected to bridge an AC power failure (emergency
battery operation).
If a 48-V direct-current system is being used instead of a battery pack for DC power
supply, connection must be performed as for a battery pack. The 48-V direct-current
system must not exceed the limit of 60 V in operating mode, during loading, and
when an error occurs. The direct-current system must not be connected to the
UPSM if this cannot be guaranteed!
Each connection must have a ferrite bead provided between the UPSM and battery
>
pack, battery cabinet or 48-V direct-current system. Insert the ferrite bead (Würth
742 7113 or C39022-Z7000-C7) with two windings into the connection cable at the
UPSM output.
You do not need a ferrite assembly when using the
sion 2 or later as the ferrite beads were integrated in the battery cabinet.
UPSM/PSUI mixed mode is only permitted in a system if the UPSM is operated without addi-
tional 48 V DC connection, that is in 110/220 V AC mode only.
Due to battery connection differences, mixed mode is not permitted in systems with uninterrupt-
ible power supply USVI. UPSM must not be implemented in these systems.
The UPSM is used in all countries. The ring frequency of the modular ring generator can be
parameterized to suit country-specific requirements. For production-related reasons there are
two different UPSM models. Technically identical, the two models have minor mechanical dif-
ferences and are fully compatible with each other.
The only exception is the UPSM model S30122-K5950-S121 which supplies a ring voltage of
60 V and is only implemented in the Republic of South Africa (RSA).
