Inserting and Removing the Bus Line
Connector
Pay attention to the following points to maintain electric
characteristics.
S8T-BUS03
Use the S8T-BUS03, which connects only the DC lines. (AC line not
connected).
S8T-BUS03 is equipped with a selector to prevent incorrect
connection to a power supply unit with a different output voltage
specification. Slide the selector to the 24 V position.
Mounting
Mounting Direction
Use standard mounting only. Improper mounting will interfere with
heat dissipation and may result in deterioration or damage to internal
parts.
Operation Check
After connecting the S8TS-06024@ and S8T-DCBU-01, it is
recommended to use the following procedure to check whether the
DC Backup Block is operating correctly.
1. Turn ON the Battery Holder.
2. Turn ON the AC power of the S8TS-06024@.

■ Functions
Charging Voltage Selector
Select either 27.4 V or 26.2 V at the
charging voltage selector to select the
charging voltage.
The shipment setting is 27.4 V.
Because the battery manufacturer
recommends 27.4 V as charging voltage, it
is recommended to charge at 27.4 V.
In this case, 27.4 VDC, which is the
charging voltage of the batteries, may
output depending on the state of
connected load when the operation mode
changes to Backup.
Note: If the battery is charged at 26.2 V, the battery capacity
