1.2 WARNING
WARNING
- Be safely dressed when handling a motor.
Wear safety shoes or gloves when handling a motor as you may get
hurt on any edge or protrusion on it or electric shocks.
- Use a crane or lift to move a motor from one place to another.
Motors are heavy. When moving them, use a crane or lift as required.
(For the weight of motors, refer to their respective specification
manuals.)
When moving a motor using a crane or lift, use a hanging bolt if the
motor has a corresponding tapped hole, or textile rope if it has no
tapped hole. If a motor is attached with a machine or any other heavy
stuff, do not use a hanging bolt to move the motor as the hanging bolt
and/or motor may get broken.
When moving a motor, be careful not to apply excessive force to its
windings as the windings may break and/or their insulation may
deteriorate.
- Do not touch a motor with a wet hand.
A failure to observe this caution is vary dangerous because you may
get electric shocks.
- Before starting to connect a motor to electric wires, make sure they are isolated
from an electric power source.
A failure to observe this caution is vary dangerous because you may
get electric shocks.
- Do not bring any dangerous stuff near a motor.
Motors are connected to a power line, and may get hot. If a flammable
is placed near a motor, it may be ignited, catch fire, or explode.
- Be sure to ground a motor frame.
To avoid electric shocks, be sure to connect the grounding terminal in
the terminal box to the grounding terminal of the machine.
- Do not ground a motor power wire terminal or short-circuit it to another power
wire terminal.
A failure to observe this caution may cause electric shocks or a
burned wiring.
* Some motors require a special connection such as a winding
changeover. Refer to their respective motor specification
manuals for details.
