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 mass.
Use motor's suspension bolts to transport the motor itself. Do not use it to transport the motor 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 motor.
Do not transport the controller or drive unit by suspending or holding the connected wires or cables.
Do not hold the front cover when transporting the 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 mass can be withstood according to the
instruction manual.
The motor does not have a complete water-proof (oil-proof) structure. Do not allow oil or water to contact
or enter the motor. Prevent the cutting chips from being accumulated on the motor as they easily soak up
oil.
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 motor. (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, drive unit or motor. Failure to observe this
could result in rupture or damage.
Do not get on the product or place heavy objects on it.
Provide prescribed distance between the controller/drive unit and inner surface of the control panel/other
devices.
Do not install or operate the controller, drive unit or motor 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 motor with the cooling fan.
Install the controller's display section and operation board section on the spot where cutting oil will not
reach.
The controller, drive unit and motor are precision devices, so do not drop or apply thumping vibration and
strong impacts on them.
Hard disk unit is a precision device, so do not drop or apply strong impacts on it.
Store and use the units according to the environment conditions indicated in each specifications manual.
When disinfectants or insecticides must be used to treat wood packaging materials, always use methods
other than fumigation (for example, apply heat treatment at the minimum wood core temperature of 56 °C
for a minimum duration of 30 minutes (ISPM No. 15 (2009))).
If products such as units are directly fumigated or packed with fumigated wooden materials, halogen
substances (including fluorine, chlorine, bromine and iodine) contained in fumes may contribute to the
erosion of the capacitors.
When exporting the products, make sure to comply with the laws and regulations of each country.
Do not use the products in conjunction with any components that contain halogenated flame retardants
(bromine, etc). Failure to observe this may cause the erosion of the capacitors.
Securely fix the motor to the machine. The motor could come off during operation if insecurely fixed.
