Default LCI starting system

My employer will be constructing two 7FA simple cycle units where im responsible to ensure the proper installation and commissioning of the LCI static starting system. Can someone explain how this control system works? any things to watch out for during the installation and testing?
Thanks for your help in advance.

Read GEs GEH instructions for the LCI in addition to how the excitation system and turbine controller interfaces with the static start control. Ensure cables are not shielded since the AC voltage can cause induced and circulating currents which ive heard of in the past burn the insulation. Verify all disconnect switch operation, ensure offline checks are working, ring out all feedback, controls, etc. before first crank. Ive seen the start up engineer put the exciter in sumilation mode and give the LCI a actual start. This would verify that all disconnect sequencing is correct in addition to the excitation system reference but not roll the unit. let me know if you need more specifics to help with your startup.
