I customised chiller performance curves of Chiller:Electric:EIR based on manufacturer's technical data.

I think the description of Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve Name in I/O Reference is incorrect. I/O Reference says that "This curve is generated by dividing the operating electric input power by the available full-load capacity (do not divide by load) at the specific operating temperatures.", but I think the curve should be generated by dividing the operating electric input power by the rated electric input power.

I think the description in Engineering Reference is correct. image description

Pleaese correct me if I'm wrong.

The nature of EIR is power (W) / cooling capacity (W), so I'm confident that the I/O Reference is correct. You might check the definition of EIR to gain confidence about this.
