Mounting and Removing Bus Line Connectors Pay attention to the following points to maintain electrical characteristics. · Do not insert/remove the Connectors more than 20 times. · Do not touch the Connector terminals. When N Blocks are linked together, the inrush current will be equal to N times that for 1 Basic Block. Be sure to use a fuse with the appropriate fusing characteristics or a breaker with the appropriate tripping characteristics. 5-V models L N Leakage Current S8T -BUS02 S8T -BUS02 The leakage current per Basic Block is 0. 35 mA at 100 VAC and 0. 7 mA at 240 VAC. When N Blocks are linked together, the leakage current will be equal to N times that for 1 Basic Block. Load Load Load Load Load Load Adjusting Output Voltage for Parallel Operation The Blocks are factory-set to the rated output voltage. When adjusting voltages, set the same values for Blocks with V. ADJ before linking them together. Adjust the set values within the limits given in the following table. Model number S8TS-06024@ S8TS-03012@ Difference between output voltages 0. 24 V max. 0. 12 V max. Mounting Mounting Direction Standard mounting Face-up mounting Other mounting methods Yes No No Use standard mounting only. Using any other mounting method will prevent proper hear dissipation and may result in deterioration or damage of internal elements. Standard mounting Face-up mounting Do not adjust voltages after Blocks are linked together. [. . . ] Do not touch the Power Supply while power is supplied or immediately after power is turned OFF. The Power Supply becomes hot and touching it may result in injury.

With the S8TS, heat is dissipated by natural convection. Mount Blocks in a way that allows convection in the atmosphere around them. *1 *1 *2 *1 *4 *1 *3 *1. [. . . ]
