*1 The input COM and output COM terminals are independent. *2 If even a single overcurrent is detected, the protection operation (output turned OFF) and automatic recovery are repeated for all outputs within the shared common, until the cause of the problem is removed. *3 The KV-N8EXT has four COM output terminals, but these terminals are shared nternally. |
