Breaker Tripping Issue during 2hp 120V Input VFD Installation

Hello, everyone!
I have recently purchased a Variable frequency drive, and I am having installation problems. The SKU is GK3000-SP1S1-1d5, and it is a 120V single phase to 1/3 phase 220V 2hp unit. I have it wired to an emergency switch and then a 20A plug, which I use for power. The unit has a green N and red L wire that I assumed was for line and neutral. The N wire goes into the unit while the L cable is spliced between 3 power input terminals. When I connect the unit to power (the motor is not connected), the breaker immediately trips even though there is almost no load on the circuit. I am wondering if the VFD is either configured for 220V or DC input, even though the sticker on the side of the unit specifically says AC 120 1ph. I believe that my wiring is correct, but it is possible that both the included L and N wires are for power in, but I just assumed line and neutral. Is my wiring correct, or does this VFD just not support 120V AC power? I have a couple of photos attached.

Hi, Callan
The GK3000-SP1S1-1d5 you purchased supports 120V input, 1/3 phase 220V output, the L/N cable is connected to your 120V power supply, and the U/V/W is connected to your 3-phase 220V motor.
About parameter setting, please refer to the parameter on the ATO YouTube channel, see on: https://www.youtube.com/watch?v=N8wYR6NmX1I&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=16

Hello, Callan
It sounds like your wiring might be shorting the input. The L and N from the cable should go directly to the input terminals (often labeled R/L and S/N), not spliced between multiple points. If you’ve tied L across multiple input terminals, that could cause an internal short and trip the
breaker immediately. Try connecting:
•L→R/L terminal
•N→S/N terminal
And leave T empty since it’s a single-phase input.

Thank you for the detailed replies! The VFD powers up correctly, and the display works as expected.
