To Wire the Repeater:
The terminal block slides into the slot on the
right side of the board. Refer to Figure 2.
1. Orient the terminal block as if you will
mount it on the board.
2. Wire the two Net A wires in the top
two positions of the terminal block.
3. Connect the ground wire via the third
screw on the terminal block.
4. Connect the 24VAC hot wire to the
forth terminal screw.
5. Wire the two Net B wires into the
bottom two positions of the terminal
block.
NOTE: Network wiring is polarity inde-
pendent, but the drawing indicates
