BFM136-RS5 suitable only with current sensors CS05S (5A/2.5A).
It is not suitable HACS 40mA.
Set CT primary 10A. Maximal measure current is 20A.
When is used additional an external CT with secondary nominal 5A, set CT Primary Current = 2 X Nominal Primary Current of the current transformer.
For example when is used current transformer 2000/5 set CT primery current 4000 in BFM135-RS5 .
For all SATEC devices: when used split core current sensors should be defined Transformer Correction in PAS as per printed Data Code on sensor itself.
