34 PowerFlex® 700S Drives - Phase I Control (Frame Sizes 9 & 10)
I/O Terminal Blocks
Wiring the Main Control Board I/O Terminals
Terminal blocks TB1 and TB2 contain connection points for all inputs, outputs and
standard encoder connections. Both terminal blocks reside on the Main Control
Board.
Remove the terminal block plug from the socket, and make connections.
Reinstall the plug, when wiring is complete. The terminal blocks have keys, which
make it difficult to insert a terminal plug into the wrong socket.
