Signal wiring is to Terminals 21 to 51. These terminals accommodate wires sizes up to 12 gauge. Please note
that the maximum torque that can be applied to terminals 21 to 51 is 0.5 Nm (or 4.4 in ·lb.) . CT, VT, and control
power connections are made using Terminals 1 to 20. These #8 screw ring terminals accept wire sizes as large
as 8 gauge. Consult the wiring diagrams for suggested wiring. A minimal configuration includes connections for
control power, phase CTs/VTs, and the alarm relay; other features can be wired as required. Considerations for
2
wiring each feature are given in the sections that follow.
