The Bi Polar fence system works by sending out two simultaneous pulses of energy down the fence line; one pulse is negative in respect to earth, the other pulse is positive in respect to earth. When installed, the energiser passes half its output voltage on to the negative charged wire and half its output voltage on to the positive charge wire.

In a Bi Polar fencing system each wire is insulated, in the same fashion as they are in a ground earth return system. The major difference being that when the wires are joined in parallel, they are joined to form two different circuits; a negative pulsed circuit and a positive pulsed circuit. See diagram. The system requires two leadouts from the energiser; one for the circuit that will be negatively pulsed and one for the circuit that will be positively pulsed.

Note: The Stafix battery range of energisers can not be used in Bi Polar Fence System.

Using the Bi-Polar system, an animal can receive a shock by:

• Making contact with the positive or the negative charged wires, thus completing the circuit through the ground earth.
• Making contact with a positive and negative charged wire simultaneously.

Setting up a Stafix Mains Energiser in a Bi-Polar system

Install the Mains Energiser on a wall, undercover and out of the reach of children. Install a ground earth system.

• Connect the insulated cable from the earth system to the half power terminal (yellow) on the Energiser.
• Connect the leadout from the negative pulsed wires to the earth terminal (green) on the Energiser.
• Connect the leadout from the positive pulsed wires to the full power terminal (red) on the Energiser.
