... Note: 1. The backup current must be less than 5 A (parallel operation connection is required if the backup current exceeds 2.5 A) and the Buffer Block must be fully charged. If three or more S8T-DCBU-02 Buffer Blocks are used in parallel operation and the backup current exceeds 5 A, the momentary power failure time that can be compensated for will be reduced. ...

... Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the specified mounting method only. Ensure sufficient heat dissipation when installing the Product to increase its long-term reliability. Natural cooling is used, so mount the S8T-DCBU-02 so that there is airflow around it. S8TS-06024 ...

... The S8T-DCBU-02 will perform the backup operation not only for momentary power failures or voltage drops, but also when the input power is OFF. The backup time is particularly long for light loads. Check the devices connected to the S8T-DCBU- sure it has stopped operation correctly. Periodic Inspection and Periodic Replacement The S8T-DCBU-02 contains built-in electrolytic capacitors, which have a limited life ...

... The voltage output from the S8T-DCBU-02 dur- ing the backup operation may be lower because overcurrent protection has operated in the S8T-DCBU-02. The input voltage to the S8T-DCBU-02 may less. A voltage of approximately higher may be input to the I/O terminals of the S8T-DCBU-02, causing the overvoltage protec- tion circuit to operate ...
