Earth grounding provides protection from electrostatic discharge or other forms of EMI.

Figure 1. Earth ground and power options

Depending on the power source used:
  • 2.1 (AC): Dedicated 24 V transformer required, with neither side of the transformer secondary tied to ground.
  • 2.2 (DC): Polarity is not important (uses onboard diode bridge), with neither leg tied to ground.
  • 2.3 (Wall-mount AC adapter, FX-SC8XPS-0) instead of wiring 24 V to 2-position connector. Do not use the wall-mount AC adapter simultaneously with power wired 2-position connector.
