Surge protection
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
Two user buttons A and B can be used for device resets
Hold Buttons A and B for 5 seconds to perform a factory reset
Hold Button A for 5 seconds to enable the Tulip Access Point
Hold Button B for 5 seconds after a plug cycle to auto-enable Tulip remote support
One reset button (resets CPU)
Heartbeat/Alert LED for device diagnostics
