5.4. HOW TO CONNECT THE WIRE TO THE TERMINALS
(1) Use crimp-type terminals with insulating sleeves as shown in the
fi
gure below to con-
nect to the terminal block.
(2) Securely crimp the crimp-type terminals to the wires using an appropriate tool so that
the wires do not come loose.
(3) Use the speci
fi
ed wires, 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.
