Sepam 50N/51N testing with CCA634 and/or CSH30

The Sepam digital relay's will have one of two connections available for a neutral CT or injection point. On Sepam relays with a CCA634 module terminals 7 and 8 will be used and secondary injection may be performed directly on the terminals. On Sepam digital relays with the CCA630 module, the only connections available are for the three line phases (A, B, and C) the neutral current must be brought to the Sepam relay via terminals 18 an 19 on the A terminal block. These terminals may not be directly injected as the signal must be converted using the CSH30, CSH120 or CSH200 module.
