HiUMENCHO, Thanks for your reply. However, my question is not on the wiring or the whole setup itself, but rather the switch setting on the power supply. Should i use parellel operation at Switch A or single operation at Switch A. Refer document:BA_6EP1437-3BA10_7

Hello, This switch is used when you put 2 Sitop in paralel to increase performance. The output voltage regulation will be affected. For redundancy you need a powersupply that can power the installation by itself, the second supply is just in case 1 powersupply breaks, therefore diodes or a module is needed. Secure 24 V DC even when a power supply unit fails Regards, Marcjan |
