Issue
Need a new CCA63x but not sure which one I need.

Product Line
SEPAM 20 Series
SEPAM 40 Series
SEPAM 50 Series
SEPAM 80 Series

Resolution
Current transformer are connected to SEPAM series 20,40 and 80 through CCA630 or CCA634 connector.
Both are including interposing CTs.

CCA630:
includes 3 interposing CTs to connect 2 or 3 phases CTs.
If CSH30 is used CCA630 is needed

CCA634:
includes 4 interposing CTs :
3 to connect 3 phases CTs
1 for the residual current acquisition (CSH30 is now integrated in CCA634 for this function) :
- the sum of the 3 CTs
- an earth/ground CT

A new SEPAM base, adding a connection for Io channel on SubD 9 connector, is needed to accept the CCA634.

THIS NEW FEATURE HAS BEEN IMPLEMENTED STARTING :
series 20 : 1st week of 2003 S/N 0301001
series 40 : week 23 of 2006 S/N 0623001
series 80 : week 29 of 2006 S/N 0629001

As modification is hardware, no firmware update can change the situation for SEPAM made before these dates.
