you use the solid core cables with the ring terminal, the ring
terminal's pressure bonding may malfunction and cause the
cables to abnormally heat up.

(1) Use ring terminals with insulating sleeves as shown in the
figure below to connect to the terminal block.
(2) Securely clamp the ring terminals to the cables using an
appropriate tool so that the cables do not come loose.

heads may be damaged and prevent the screws from being
properly tightened.
(5) Do not tighten the terminal screws too much, otherwise, the
screws may break.
