1. Usage
WARNING
The MELIPM series motor is a synchronous motor with high-performance
magnets built in its rotor. Therefore, after the drive unit is powered off, there
are high voltages at the motor terminals while the motor is running. Before
starting wiring or maintenance and inspection, make sure that the motor has
stopped. In any application where the motor is rotated by a load such as a
fan or blower, connect a low-voltage manual switch on the drive unit's output
side, open the switch, and start wiring or maintenance and inspection. Not
doing so can cause an electric shock.
Never disassemble or modify the unit. Doing so can cause an electric shock,
fire or injury.
Do not use the unit with any load other than the specified motor. Doing so
can cause a fire or injury.
Provide safety devices for the whole system, e.g. emergency brakes, to
ensure that the machine or device is not placed in hazardous conditions
when the drive unit fails.
CAUTION
If a holding brake is required, prepare it separately. Injury may result.
Before operating the drive unit which had been stored for an extended
period of time, perform inspection and test operation on the unit before
using. Not doing so may cause accidents.
2. Transportation
CAUTION
Do not stack the drive unit boxes higher than the number indicated on the
package. Doing so can cause injury.
Confirm the weight before carrying the drive unit. Not doing so can cause
injury.
When carrying the drive unit, do not exert a force partially, i.e. do not hold
the front cover. Doing so can cause the unit to drop, leading to injury.
The drive unit is precision piece of equipment. Do not drop it or subject it to
impact, this may damage the drive unit.
3. Installation
CAUTION
Do not install or operate the drive unit if it is damaged or has parts missing.
Such installation or operation can cause accidents.
Always install the drive unit in the specified orientation and environment. Not
doing so can cause a fire or accidents.
Install the drive unit on an incombustible material such as metal. Not doing
so can cause a fire.
Do not place combustible materials nearby. Doing so can cause a fire.
Install the drive unit in a load-bearing place. Not doing so can cause
accidents.
Prevent screws, metal pieces or other conductive foreign matter, or wood
scrap, oil or other flammable foreign matter from entering the drive unit.
They can cause a fire or accidents.
