Commissioning
Before you switch on the supply voltage, verify that the
operational data match the rated data on the name
plate and the technical data according to Chapter 18.
This applies in particular to the supply voltage V
H
and
to the maximum current and voltage values of the
device. After an operating time of approximately
15 minutes, the device will stay within the tolerances
specified in the technical data.
The delivery includes a lithium battery that powers the
battery-buffered memory and the real-time clock. Upon
delivery the battery is insulated in the battery
