Note 1: Though the Terminal Block supports CT shorting, it is highly recommended to short CT by
external means before removing relay from system;
Note 2: For 5A CT secondary, we recommend using 2 x 2.5 mm2 PVC insulated multi-stranded
copper wire.
2.3.11 Output Relay Connections
These should be wired with 1 mm PVC insulated multi-stranded copper wire terminated with
pin type lugs.
2.3.12 USB Connection
The IED has a type B USB socket on the front panel. A standard USB printer cable (type A
one end, type B the other end) can be used to connect a local PC to the IED. This cable is
the same as that used for connecting a printer to a PC.
