7.3. How to connect wiring to the
terminals
Caution when wiring cable
When stripping off the insulation of a lead wire, always
use a special tool such as a wire stripper. If there is no
special tool available, carefully strip the insulation with
a knife etc.
(1) Use crimp-type terminals with insulating sleeves as
shown in the ¿ gure below 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.
Strip : 10 mm (13/32 in.)
(3) Use the speci¿ 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, oth-
erwise, the screw heads may be damaged and prevent
the screws from being properly tightened.
(5) Do not tighten the terminal screws too much, other-
wise, the screws may break.
