WARNING
When using solid core cables, do not use the ring terminal. If you use the solid core cables
with the ring terminal, the ring terminal's pressure bonding may malfunction and cause the
cables to abnormally heat up.
B. For strand wiring
(1) Use ring terminals with insulating sleeves as shown in the
fi
gure below 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 speci
fi
ed 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 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 for the terminal screw tightening torques.
(7) Please do not
fi
x 2 power supply cables with 1 screw.

CAUTION
To peel the

lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening the
screw. On the other hand, an undertightened screw can cause faulty contact, which will
lead to a communication failure.
