*1. Refer to Output Voltage Adjustment for S8TS-06024[] on Catalog.
*2. The output specifications are defined at power output terminals.
*3. Specified by performance of S8TS-06024[] Basic Block.
*4. Specified by S8TS-06024[] connection.
*5. The output voltage will be 21.0 V (min.) when switching to backup operation.
*6. The life of the battery will greatly reduced when operating below the minimum output. Design the loadcircuit so that
at least the minimum output is maintained.
*7. Refer to Backup Time (Reference Value) on Catalog.
*8. Refer to Functions on Catalog for details.
*9. Set the detection current to 20 mA × N, where N is the number of S8TS-06024[] Basic Blocks connected.
*10. Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.
*11. To ensure Class 2, take one of following measures.
Note that the number of S8TS-06024[] to be connected to the S8T-DCBU-01 shall be one.
• Connect S8T-DCBU-01 to S82Y-TS01 having its fuse replaced with an UL-Listed and DC rated 32 VDC min./3 A
