For power input terminals, use 35 A max. per pole. *2. A voltage drop will occur in the S8V-CP. Consider the voltage drop at the output. *3. When selecting the power supply, be sure to include the power consumption of the S8V-CP and not just the power consumption of the load. *4. Outputs start in order from +VO1 to +VO8. +VO1 starts after the initialization time. Start-up delay time of each output is automatically decided depending on the load. If the start-up delay time is over 5 s, the next output is forcibly started. *5. Refer to Tripping Functions on page 3 for details. *6. Refer to Current Tripping Characteristics and Current and Voltage Tripping Characteristics on page 7 for details. *7. MTBF is calculated according to JEITA RCR-9102. *8. Refer to Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance on page 14 for details. *9. UL Class 2 output applies for the S8V-CP0424S model only. 2
