POWER_INHIBIT Inhibit input
Table 4: Global Reset Connector Pin Assignment
The signals shall be connected by an isolated contact (e.g. relays), and must not be connected
to other potentials.
The input has an internal 10 kΩ pull-up resistor to 5V and an input impedance of 10 kΩ.
It is possible to invert the logic of this signal by changing a jumper switch inside of the
power box..
