SEPAM With a CCA634 Sensor Connector : on which SEPAM can I use it ?
Answer :
Current transformer are connected to SEPAM series 20,40,and 80 through CCA630 or CCA634 connector.
Both are inclunding interposing CTs.
CCA630 includes 3 interposing CTs  to connect 2 or 3 phases CTs.
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.
