• When stripping off the coating of a lead wire, always use a special tool such as a wire stripper. If there is no special
tool available, carefully strip the coating with a knife etc.
How to connect wiring to the terminal
Caution when wiring cable
(1) Use crimp-type terminals with insulating sleeves as
shown in the figure to connect to the terminal block.
(2) Securely clamp the crimp-type terminals to the wires
using an appropriate tool so that the wires do not come
loose.
(3) Use the specified 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.
