(Abnormal heating may occur if the wirings are not
tightened securely.)
• Use the required wirings, connect them securely and fix
these wirings securely so that external force may not apply
to the terminals.
• Use a proper screw driver for tightening the terminal screws.
If an improper screw driver is used, it may damage the
screw head and a proper tightening cannot be carried out.
• If a terminal is over tightened, it may be damaged.
Refer to the table shown below for tightening torque of
terminals.

• Do not carry out soldering finish when stranded wirings are
used.
WARNING
• When wiring, form the wirings orderly so that the control
box lid can be securely fastened. If the control box lid is
not in place, the wirings may come out or be sandwiched
by the box and the lid and cause electric shocks or a fire.
