Connecting Omega Hot Wire Anemometer to STG

Hello,

I would like to connect to the anemometer pictured below to a STGv2 slice. The PWR +, PWR -, and Analog Output pins are all that need connection to operate, we do not need the alarm functions. I would like to supply excitation from the slice.

I believe I need to connect the Analog Output pin to In + (2), PWR - to Exc - (8), and Exc + (1) to PWR +. I am concerned about connecting In - (7) to PWR - if I am also using it for excitation supplied by the slice. I am wondering if I alternatively need to connect PWR - to Gnd (4), or if I need to re-think this.

Thanks
