The inhibit-input disables buffering. In normal mode, a static signal is required. In buffer mode, a pulse with a
minimum length of 250ms is required to stop buffering. The inhibit signal is stored and can be reset by cycling the
input voltage.
For service purposes, the inhibit input can also be used to connect a service switch. Therefore, the inhibit signal can be
supplied from the output of the DC-UPS.
