How to connect wiring to the terminal
Caution when wiring cable
(1) Use ring terminals with insulating sleeves as shown in the figure 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.
(3) Use the specified cables, connect them securely, and fasten them so that there is
no stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal screws. Do not use a screw-
driver that is too small, otherwise, the screw 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.
(6) See the table below for the terminal screw tightening torques.
