Battery/Power supply
CPU iput “Ext. Batt.” incl. cable
Ca
≥
Ci + Cc (25nF + Cc)
La
≥
Li + Lc (2mH + Lc)
The batteries used must have the following properties:
•
Battery technology: Li/SOCL2
•
Model: AA
•
Voltage: 3.6 V
The batteries stipulated by Siemens fulfil requirements that go beyond the ones
mentioned above.
You may only use batteries approved by Siemens !
Note
If you do not know the capacity and inductance of the cable, you can use the
following values:
Cc = 197 pF/m (60 pF/ft.), Lc = 0.66 pF/m (0.2 mH/ft)
Example
The battery of type 4022 from Varta together with a 1.5 m long cable and a plug
connection of type 02–02.1500 from Leonhardy meet these conditions.
