7. VFD-M-D series is the specific drive for the elevator door and other automatic door control,
NOT for those devices that may cause personal injury, such as life support equipment or any
life safety situation.
8. VFD-M-D is produced with strict quality management. It will need the safety device when it is
used in those occasions that may cause severe accident due to the malfunction.
WARNING!
1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor
drive is easily damaged by high-pressure.
2. There are highly sensitive MOS components on the printed circuit boards. These components
are especially sensitive to static electricity. To prevent damage to these components, do not
touch these components or the circuit boards with metal objects or your bare hands.
3. Only quality person is allowed to install, wire and maintain AC motor drive.
CAUTION!
1. Some parameter settings will cause the motor to run immediately after applying power.
2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,
high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic
particles.
3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or
electric shock.
4. To prevent personal injury, please keep children and unqualified people away from the
equipment.
5. When the motor cable between the AC motor drive and motor is too long, the layer insulation of
the motor may be damaged. Please use a frequency inverter duty motor or add an AC output
reactor to prevent damage to the motor. Refer to appendix B Reactor for details.
6. The rated voltage for the AC motor drive must be ≤ 240V and the mains supply current capacity
must be ≤ 5000A RMS.
