Note that some items described as
CAUTION
may lead to major results depending on the situation.
In any case, important information that must be observed is described.
DANGER
[General]
Do not use this motor in an explosive atmosphere. Use an explosion-proof motor for that type of atmosphere. Failing to observe
this could lead to injuries or fires, etc. (Refer to page 2.)
Do not work with a live wire state. Always turn the power OFF before starting work. Failing to observe this could lead to electric
shocks. (Refer to page 7.)
Only trained persons must perform transportation, installation, piping and wiring, operation, maintenance and inspection. Failure
to observe this could lead to electric shocks, injuries or fires, etc. as well as motor damage or failure. (Refer to page 7.)
[Piping and wiring]
Always follow the connection drawing in the terminal box or the Instruction Manual when connecting the power cable. Failure to do
so could lead to electric shocks or fires. (Refer to page 8.)
Do not bend, pull or catch the power cable or motor lead wires with force. Doing so could lead to electric shocks. (Refer to page 8.)
[Installation and adjustment]
Always ground the grounding terminal. Failure to do so could lead to electric shocks. (Refer to page 7.)
When installing the motor on a ceiling or wall, it could fall depending on the circumstances. Refer to the catalog or technical
documents for details on the applicable range. Failure to observe this could lead to injuries. (Refer to page 2.)
[Operation]
Do not operate the motor with the terminal box cover removed. After work, return the terminal box cover to its original position.
Failure to do so could lead to electric shocks. (Refer to page 9.)
Never go near or touch the rotating parts (shaft, etc.) during operation. Failure to observe this could lead to entanglement or
injures. (Refer to page 9.)
Always turn the power switch OFF if a power failure occurs. Failure to do so could lead to injuries. (Refer to page 9.)
[Maintenance and inspection]
Always follow the connection diagram in the terminal box or the Instruction Manual when connecting the power cable. Failure to do
so could lead to electric shocks or fires. (Refer to page 8.)
