    Question connecting three-phase power cable from the power grid to the Mazak transformer

    Hello!

    I have a question. The three-phase power cable from the power grid is written on the transformer switch where I need to connect the L1, L2 and L3 wires, but where I need to connect the N Null wire?

    And I found an secondary transformer (mounted on the top) KMF3100 100A, 520 V, 56/60HZ, it has no electrical cable connected (only the ground). What is it used for? I have Mazak SQT250 Lathe.

    Thank you!
