Field circuit and ground connection
The unit contains a semi-controlled single-phase motor field power supply circuit. As shown, the input and output
connections are in the lower part.
We recommend the use of an adapter transformer for the input power supply to terminals U1-V1. The fuses
listed in the table are mandatory.
Use dip-switches S14 on the regulation card to set the field current full scale value, see "Table 2.3.3.4-F: Field
current resistors Sizes TPD32-EV-CU-..." on page 32

Interface with three-phase power supply (mains) and motor armature voltage
The CU requires a mains voltage and armature voltage feedback from the controlled power bridge. It is connected
to terminals U V W and C D, respectively, of the KP connector. As mentioned previously, the CU is supplied
with a specific cable already fitted with the relative KP connector at the CU end and free conductors at the other
end (“KP connector interface cable for TPD32-EV-CU”, EAM2762).
