NV350 Handbook
The following nomenclature may optionally be used for outputs connected in series:
(Note that outputs may be connected in series even when this nomenclature is not used)
@BB or @ BHB or @BBH or @BHBH or @CC or @CCM
where @ is the total voltage of any two B, BH, C or CM modules connected in series.
or
@/#BDB or @BHDB
where @ is the total series voltage of any B or BH module and DB module channel 1. # is the output voltage
of the DB module channel 2. Voltages for # are within the range given in the DB module tables.
or @HDB
where @ is the total series voltage of any DB module channel 1 and channel 2.
For all outputs connected in series:
Permissible min. value for @ is given by summing the min. voltage ratings of the outputs connected in series.
Permissible max. value for @ is given by summing the max. voltage ratings of the outputs connected in series.
