7 Replacement of communication modules
A faulty communication module can be substituted by another communication module of the
same type by the customer on site. It depends on the software version of the EK260 and on the
type of the communication module if the new module can be parameterised on site or if it must be
parameterised by Elster-Instromet exworks (refer to the table in chapter 6).
The replacement of a communication module by another communication module of a different
type (e.g. analogue modem replaced by ISDN adapter) can only be carried out by Elster-
Instromet exworks or by Elster-Instromet´s customer service.
