WARNING!
Setting current transformers characteristics on the
Current Transformers Menu does not provide the
correct operation of CPM 310 G by itself; but also, the
dip-switch settings must also be done! Incomplete and
inappropriate settings on the menus and dip-switches
may result in secondary protection, selectivity and
supply continuity failures, performance drops and
misinterpretations!
Please see the Dip-Switch Settings section for detailed
information on the secondary signal processing
principles of CPM 310 G, at p.47 of this manual. □
