Installation Instructions
that the main voltage can be switched off. This can be done manually via a
signal lamp connection or via a contactor. With this solution the main
switch generally only has to be switched off if the control cabinet has to be
opened. The battery will only be used in the event of a power failure.
In order to maintain a screen display for the Industrial PC in the event of a
power failure, the power supply unit is equipped with a UPS output 27 V /
1.4 A (max. 2.5 A from 2016 and later) for connecting a Control Panel with
a display dimension up to 19 inches. This enables a power failure to be
visualized and displayed to the user. Once the PC has shut down, the UPS
output is switched off.
For a detailed functional description please refer to section Connecting
Power Supply.
