Notes on voltage measurement
Current / voltage measuring modules must
be used with a decoupling module in certain
types of power system. See the table in
Chapter
Decoupling module (DCM) for
1st generation current/voltage measuring
modules (e.g. 3UF711.1AA000) (Page 142).
Note that the supply cables for voltage measurement may require additional
cable protection.
