The Grid 1 and Grid 2 terminal blocks connect the Terminal Assembly to the power
systems being measured.
Each side of the Terminal Assembly has a 12-position terminal block for user connections.
The screw terminals accommodate solid or stranded wires from 8 – 18AWG
The following table lists the Grid 1 and Grid 2 signal inputs to the Terminal Assembly. The
Grid 1 common (COM1) and Grid 2 common (COM2) are internally connected and must
