4. General Precautions
Always follow the precautions below. Incorrect handling could result in faults, injuries or electric shocks, etc.
(1) Transportation and installation
Correctly transport the products according to the weights.
Use servomotor's suspension bolts to transport the servomotor itself. Do not use it to transport the servomotor
after installation onto the machine.
Do not stack the products exceeding the indicated limit.
Do not hold the cables, shaft or detector when transporting the servomotor.
Do not transport the controller or servo drive unit by suspending or holding the connected wires or cables.
Do not hold the front cover when transporting the servo drive unit, or the front cover could come off, causing the
unit to drop.
Install on a non-combustible place where the unit's or motor's weight can be withstood according to the
instruction manual.
The servomotor does not have a complete water-proof (oil-proof) structure. Do not allow oil or water to contact
or enter the motor. Prevent the oil-soaked cutting chips from being accumulated on the motor.
When installing the motor facing upwards, take measures on the machine side so that gear oil, etc., will not
enter the motor shaft.
Do not remove the detector from the servomotor. (The detector installation screw is treated with sealing.)
Do not allow foreign matters, especially, conductive foreign matters such as screws or metal chips, or
combustible foreign matters such as oil, to enter the controller, servo drive unit or servomotor. Failure to
observe this could result in rupture or damage.
Do not get on the product or place heavy objects on it.
Provide appropriate distance between the controller/servo drive unit and inner surface of the control panel/other
devices.
Do not install or operate the controller, servo drive unit or servomotor that is damaged or has missing parts.
Take care not to cut hands, etc. with the heat radiating fins or metal edges.
Do not block the intake/outtake ports of the servomotor with the cooling fan.
