ure of the supply voltage does not effect the initialization phase of the connec-
ted PC in any way).
Switch position 8 and 9
After the input voltage has been switched off, the UPS is in UPS mode. The PC
shuts down and switches the power supply unit in the PC off after the operating
system has been shut down successfully. The switch off of the power supply
unit voltages is detected by the UPS via the +5 V voltage of the USB interface.
The UPS switches the output voltage off. Consequently, the input voltage of the
connected PC is also switched off immediately.
The UPS with the connected PC can be switched on immediately and an new
switch on cycle starts.
If switching off of the +5 V voltage of the USB interface is not possible after
shutting down the PC, an internal timer switches the UPS off.
This function extension can only be used if the USB connection be-
tween UPS and IPC is established.
We recommend the switch positions 1 to 3, 8, 9 for the production
mode.
The time, which is set by the switch, has to ensure that the system/
station including the applications can shutdown completely.
Switch position 4 to 7 (for commissioning)
If switch positions 4 to 7 are used, the timer (time delay of 120 seconds) inte-
grated in the UPS is switched off. Thus, unnecessary waiting times, e.g. during
commissioning, are avoided. After commissioning reset the switch to the switch
positions 0 to 3.
We recommend switch positions 4 to 7 exclusively for commission-
ing to avoid waiting times.
