Usage

  • Use either a Tulip provided Factory Kit power supply or a regulated 24V input

Grounding and Earth Connections

  • Chassis (including the DIN mount) and 24V Return are internally connected
  • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth
  • Input banks A and B on the Gateway feature an additional grounding pin reference to the 24V return for convenience

Recommendations

  • In production, DIN rail should be held at earth potential.
  • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth.
