Disconnect all cables from the terminals to. Remove the old PCB.
Also make sure that you have connected the cables from the thyristors
in the correct position differ from the old PCB DS

Replacing PCB marked Rev revision (Not valid for 690V). Mount the cable the PCB from the
thyristors, fans and thermal switch.
This chapter valid replacing broken with newer revision (rev later) PCB.
