8.6 Decoupling module (DCM) for 1st generation current/voltage
measuring modules (e.g. 3UF711.1AA000)
Function of the decoupling module
When measuring voltage and power with SIMOCODE pro in ungrounded networks, each
current / voltage measuring module must have a decoupling module connected upstream in
series at the system interface. Where voltage or power is measured with SIMOCODE pro in
systems with additional insulation measurement or insulation monitoring, a decoupling
module must be connected between the basic unit and each current / voltage measuring
module. If using the 3UF710 current measuring module in these networks, it is imperative
that an additional decoupling module is not used.

Note
Connectable expansion modules
When using a decoupling module, note that the type and number of expansion modules that
can be connected to a basic unit are limited! See Chapter
Configuration information for
SIMOCODE pro V when using
an older basic unit (Page 155).
Note
Using the decoupling module
Do not use the decoupling module with the 2n
d generation current / voltage measuring
generation current / voltage measuring module is replaced by a
generation current / voltage measuring module, remove the decoupling module.
