Pins 8-13 are internally connected to the magnetic shield around the Hall core. The reveals that leaving these floating invites noise. The correct method (per the new diagram) is to connect these pins to chassis ground via a 1MΩ resistor + 10nF capacitor in parallel. This drains static charge without creating ground loops.
