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.

User I/O
