•G+ Mini includes a 24VDC interface board and optionally ships with an adder AC interface board,
allowing direct connection of 24, 42-48, or 120 VAC user input devices. The interface board connects to VFD
terminals S1-S7 and SC. The user input device then connects to terminals S1-S7 and X2 (or SC on the 24VDC
interface board) on the interface board. Terminals S1 and S2 are factory programmed for the forward (up) and
reverse (down) run commands; however, they can be programmed for speed control and other functions like the
remaining terminals. The figure below shows the control terminal arrangement for the IMPULSE
