UPSC-DR 
 

Introduction  
The UPSC-DR board (S30122-K7373-A900, S30122-K7373-M900 (Figure 3-26)) is used in HiPath 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 "Inserting Powerbox PB3000").
Warning  
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  
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 (Power box 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 battery 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  
4 x V39113-W5123-E891 (4 x 12 V/7 Ah batteries)
These are the only batteries released for connection to UPSC-DR and installation in Powerbox PB3000.
Danger  
Do not use 24-V batteries (S30122-K5403-X) in conjunction with UPSC-DR as an explosive gas (hydrogen + oxygen) escapes when the battery is overloaded.

Switches and indicators  
Caution  
System voltage can only be switched on or off by plugging in or out the power plug. If using an uninterruptible power supply, switch off the battery voltage first.  
 •   LED, green: +5-V output voltage is available.
 •   LED, yellow: -48-V output voltage is supplied by the external power supply (Powerbox PB3000 with LUNA2).
 •   Slide switch for setting the ring frequency:
- 25 Hz (GER + international market)
- 20 Hz (U.S.)
- 50 Hz (FKR)
 •   Slide switch for activating and deactivating the battery voltage (batteries):
   -   up = off, battery voltage deactivated (battery backup off)
   -   down = on, battery voltage activated (battery backup on)
