How to connect wiring to the terminal
Caution when wiring cable
(1) Use ring type terminals with insulating sleeves as shown in the fi gure to connect to
the terminal block.
(2) Securely clamp the ring type terminals to the wires using an appropriate tool so that
the wires do not come loose.
(3) Use the specifi 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
screwdriver 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.
