Connection Example for 7XR81
Refer to the user manual of the 7UM62/7UM85 protection relay for details on commissioning the coupling
unit.
NOTE
The inductor L1 can be connected in series between the output 8A and the input current of the protection
relay in order to reduce high ripple noise injected by some excitation regulators.
NOTE
•
The fuse F1 must be rated for 250 V AC, 1 A T (time-lag).
•
The fuses F2/F3 must have at least the rated voltage of excitation (e.g. 1000 V DC) and be rated for
0.6 A T (time-lag).
