*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 internally.
