Delivery state: Wire jumper between pin 9 and 10
Interruption of the output voltage (pin 13)
A wire jumper on the signal connector ④ between pin 13 and pin 10 is used to
enable/disable the interruption of the output voltage for the parameterized time (default value
5 seconds) for supply system restoration during the buffer time.
To prevent data losses, the PCs must be shut down timely before the buffer time ends. If the
input voltage returns after the shutdown has already started, buffer mode is ended and the
UPS1600 goes into normal operation. The PC will be shut down, however, it is not switched
off. PCs, which do not have an on/off switch, can only be rebooted by switching off the power
and switching on again.
For customers that use their own software, this pulse must be selected at the DC UPS
module.
Note
This function is possible only in conjunction with the R signal (DC UPS Ma
nager).
