Questions re Blue Solar 75/15 MPPT controller

I purchased and am waiting to receive my Blue Solaris 75/15 MPPT charge controller.
I have two questions about that device, while reviewing the user manual online:

  1. For the wire connection terminal block, what is the proper wire gauge that will fit into the square terminal block openings? I don’t see this specified in the user manual.

  2. I will be using a LifePo4 Lithium Iron Phosphate battery, 12 volts 50 AH. I can’t see in the user manual installation and config sections where I specifically set up the controller for LifePo4 batteries? Is there a setup flow chart or step by step order? Something like, first connect ONLY the battery to the controller, and then use your phone to connect to Bluetooth, and then configure the following settings for LifePo4 BEFORE connecting the PV solar panels? I am not clear on what steps to take after reviewing the user manual.

Sincere Thanks for any guidance/mentoring,

Neal

In the manual you can see the order of connection

While you are connected over VictronConnect you can also adjust the charging parameters already, theres a Lifepo preset if no details are specified by the battery manufacturer.

Terminals are specified up to 6mm² / AWG10, multistranded flexible wiring
