6.3 Funcionamiento general
Once installed and configured, the device operates automatically. It continuously monitors voltage and current. If a parameter exceeds or falls below the set limits, the protector will instantaneously cut off the power supply to protect connected equipment. When conditions return to normal, the device will automatically re-engage the power supply after the set recovery delay time.
