Important: The set time has to be greater than the time the PC requires for a
controlled shut down. A sufficient time reserve has to be taken into consider-
ation.
The checkbox "Enable Shutdown on COM fail" must not be activated in the
UPS software (UPS NT Control Software) running on the IPC.
Disadvantage: If the time span is too short, uncontrolled standstill of the sys-
tem can occur. Sporadically, the IPC cannot be started anymore due to loss
of data.

VAU 01.1S and VAU 01.1Z
Recommended rotary switch 1 to 3 for IPC series:
– VSxxx.1
– VSxxx.3
Advantage: The RS232 interface between UPS and IPC has a very high EMC
resistance (previous standard).

12 Device Description
12.1 General Information
The VAU 01.1U, VAU 01.1S and VAU 01.1Z are UPS (Uninterruptible Power Sup-
plies), which provide power to the connected device for a limited time if the
supply voltage fails (DC 24 V).
The UPS can provide the connected device with 24 V and 10 A (2.5 A for VAU
01.1Z) for max. three minutes (VAU 01.1U from technical index GC1: six). The
communication between UPS and panel PC or control cabinet PC occurs on the
VAU 01.1U via a USB interface (XUSB In) , and on the VAU 01.1S and VAU 01.1Z
via a RS232 interface (XCOM1).
The UPS consists of the following components:
●
Enclosed metal housing
●
Battery integrated in the device (VAU 01.1U and VAU 01.1S)
●
Integrated power supply unit (VAU 01.1Z)
●
Display and operating components on the front panel.
●
Integrated burst and surge protection for the connected device.
