Connections at the back side
The LZE-III has an internal uninterruptible power supply (UPS). Write operations in progress to the Compact Flash board are
terminated normally and no new write operations begun during interruption. The buffer capacity of the UPS is sufficient to op-
erate the LZE-III for a maximum of 5 seconds with the monitor switched off. During current interruption, the monitor and the
USB port are switched off. Touchscreen entries are not possible during this time. Central unit LZE-III starts normally when the
regular power supply is available again.
