The compliance voltage at the rated output current is 10V.
The transformation ratio of the current transformers is 2000 : 1

When measuring equipment is connected to the unit, the effective load impedance and thus the voltage will
vary in accordance with the internal resistance of the equipment.
For the lowest rated output current of Type E units, 142A, jumpers J1 to J4 should be closed and J5 to J14
open. For the maximum rated output current of 605A, all jumpers (J1 to J14) should be closed.
Example: For a unit with a rated output current of 222A, jumpers J7 to J14 should be open.
Replacement units are supplied with all jumpers closed (J1 to J14). Before start-up the unit, therefore, the
jumpers should be positioned as appropriate to the rated output current (see rating plate) and accordance
with Table 9.6.
