(1) Before connecting electric wires, be sure to turn off the power
switch.
Never do this work with voltage applied.
(2) Securely connect to ground. There is a risk of an electric shock in
the event of a breakdown or leakage of electricity. The earth terminal
on the motor is the screw indicated by the "Earth Mark" in the
terminal box. The wire diameters of the power cord for supplying
power to the motor and the power cord connected to ground shall
be the same.
(3) Do not use at a voltage other than the motor's rated voltage.
Otherwise overload protective equipment does not work correctly,
which may result in a motor burnout or fire.
(1) Be sure to install overload protective equipment suitable for the
motor capacity. To prevent a motor burnout, install overload
protective equipment in the electric connections. If overload
protective equipment is not installed or it is installed but not
suitable for the motor capacity, a motor burnout or fire may occur.
We recommend installing protective equipment (such as an earth
leakage breaker) in addition to overload protective equipment.
(2) Do correct wiring work according to the electrical equipment
technical standards and indoor wiring regulations. Wrong wiring
work may trigger fire.
(3) Use an appropriate electric insulated wire for the power cord which
can tolerate the above rated current value.
(1) The motor's rated current value depends on the motor
manufacturer. Use overload protective equipment that works at the
rated current of the motor you use.
(2) Make the connections for full-voltage start. Otherwise it may be
difficult to start with a star/delta connection.
To prevent a motor burnout due to overcurrent, install overload
protective equipment in the electric connections. If overload protective
equipment is not installed or it is installed but not suitable for the motor
capacity, a motor burnout or fire may occur.
