If the reset is supposed to be controlled by the PC or another external trigger and not the DC-UPS, the following
wiring option is possible but requires an external relay:

Activation of the “external control mode”:
The PC-Mode pins need to be connected together during a normal mode operation. This connection must be opened
within the first second of a buffer event to set the DC-UPS into the “external control mode”. In this mode, a signal on
the inhibit input will not immediately execute a shut-down of the DC-UPS’s output but will be delayed by 70s. The
output of the DC-UPS will always be switched off for at least 5s.
