Electronic apparatus, especially central unit of programmable storage control unit, has second battery plug and in its leads, for connection of battery plugs with data store, decoupling resistances are inserted

摘要

The electronic apparatus has a first battery plug (2) for the connection of a back-up battery (3) for the supply of a data store (4), especially a RAM. In a first connecting lead (21,22) for the connection of the first battery plug with the data store, a decoupling resistance (6) is inserted. A second battery plug (5) is provided. In a second connecting lead (51,52) for the connection of the second battery plug with the data store, a second decoupling resistance is inserted. The connecting leads of identical poles are wired in parallel.
