Backup Function
S8T-DCBU-01 detects output voltage drop of S8TS-06024@ to
switch to backup operation.
Backup operation continues for about 7 seconds even after the
output voltage of S8TS-06024@ is restored.
Note: (1) If this state occurs, the S8TS-06024@ may be overloaded or malfunctioning.

Output Voltage Adjustment for
S8TS-06024@
The DC Backup Block detects a drop in the output voltage (approx.
23 VDC) of the connected S8TS-06024@ to switch to backup
operation.
The output voltage of the S8TS-06024@ can be adjusted using the
output voltage adjuster. Do not, however, set the output voltage to
lower than the factory shipment setting, if the S8TS-06024@ is used
connected with a DC Backup Block.
Wiring Length between S8T-DCBU-01
and Battery
Connect S8T-DCBU-01 and the battery using a cable having a wire
diameter specified in Recommended Wire Diameter on page 16
within a wiring length of 1.5 m.
Because the battery voltage is monitored at the battery connecting
terminal, a large wiring impedance increases the voltage drop from
wiring, reducing the backup time.
Battery Holder S82Y-TS01
We recommend using the S82Y-TS01 Battery Holder for connecting
and installing the battery. Take the following points into consideration
when using the S82Y-TS01:
(1) Contact between leaking battery fluid and metal parts having an

switched to. The peak value and time of this inrush current vary
according to the capacity of the input capacitor of the connected
equipment, battery charge status, battery wiring length, and
ambient temperature. The switch and fuse of the S82Y-TS01 are
selected taking this inrush current into consideration. When
replacing the fuse, use only the specified fuse. (Littelfuse,

the battery still connected, the standby current of the S8T-DCBU-
0 may cause the battery to discharge, considerably reduce the
service life of the battery, and render recharging and backup
impossible. To prevent this, turn OFF the switch. (Refer to Bat-
tery Overdischarge on page 4.)
