4.5.2 Connection of CTs of other manufacturers

External transformers can only be used with the respective function module activated. The wind-
ing number of the external transformer absolutely must be entered (registers 33104...33107).
Use residual current transformers and not load-current transformers.
Response range
The maximum response range is 6 mA ... 30 A. The actual upper limit of the response range de-
pends on the number of windings of the measuring-current transformer used:
Measuring range
The upper limit of the measuring range depends on the number of windings n of the measur-
ing-current transformer used:
Measuring range upper limit
Continuous residual current
The permissible continuous residual current depends on the number of windings n of the meas-
uring-current transformer used:
permissible continuous residual current
permissible continuous secundary current

Compliance with the respective product standard under „8.3 Standards & certifications"
cannot be ensured if an external transormer is used and, if necessary, needs to be as-
sessed separately after consultation with the manufacturer.
