UPSC-DR

Introduction
The UPSC-DR board (S30122-K7373-A900, S30122-K7373-M900 (Figure 3-26)) is used in Hi-
Path 3500 and HiPath 3300 (19-inch housing).
This module supports power supply and battery management functions. No other components
are required if it is operated as an AC power supply. To maintain short-term battery emergency
operation after a power failure, that is, to use uninterruptible power supply functions, you must
also connect a battery pack (see Section 9.1.3).
Warning
7
The UPSC-DR power supply unit is only released for permanent AC power supply.
Permanent 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
UPSC-DR if this cannot be guaranteed!
Danger
7
The UPSC-DR board is not insulated.
Consequently, a system using a UPSC-DR may only be operated with a closed
housing.
Before opening the housing, make sure that the system is de-energized as follows:
by disconnecting the battery voltage and line voltage at any connected PB3000.
●
by disconnecting the line cord attached to any connected batteries (PB3000).
●
by disconnecting the line cord attached to any connected Powerbox PB3000.
●
by disconnecting the power plug.
●
If the power supplied by the UPSC-DR is insufficient, an external power supply
PB3000 with LUNA2) can be installed to provide additional power. To do this, connect the DC
port on the PB3000 to the special -48-Vdc input on the UPSC-DR. The UPSC-DR's internal -
48 V output is deactivated when the external power supply is connected. For emergency bat-
tery operation in the event of power failure, 4 x 12-V/7-Ah batteries (4 x V39113-W5123-E891)
must be installed in the Powerbox PB3000.
Licensed batteries for UPSC-DR
