Step3: Change rated current (1A 5A)
Pull out VCT module from the IED case.
To shift the rated current to 1A, remove jumpers shown in Table 13.4-2.
To shift the rated current to 5A, insert jumpers shown in Table 13.4-2.
To identify the VCT type, see the code at Position 7; look up the VCT type in Table 13.4-2.
For example, the IED below has VCT12B because the code at Positon 7 is printed “1”.
VCT12B is mounted in the case

Step5: Check altered ordering code, which is set on Step 2†.
The user needs to confirm the rated current changed by checking the altered ordering
code (at Position K)‡. Figure 13.4-1 illustrates how to confirm the altered ordering code
from the nameplate and LCD screen.
