Emotron VSB Instruction Manual Chapter 1 Safety Precautions
1.2 Other Considerations
1.2.1 Input Power Supply
This series of drives are not applicable to applications out the range of operating voltage as set
forth in this manual. If necessary, please use booster to rise or drop the voltage to regulated
voltage range.
1.2.2 Surge Protection
This series of drives are furnished with surge suppressor that has certain resistance to lightning
induction. However, users in areas with frequent occurrence of lightning need to mount an
external surge suppressor in front of the drive power input side.
1.2.3 Operation of Contactor
As to the configuration of peripheral devices recommended by this manual, it is necessary to
mount a contactor between the power supply and this drive input side. Such a contactor should
not be used as a control device for start and stop of the drive, as frequent charging &
discharging shall reduce the service life of internal electrolytic capacitors.
When it is necessary to mount a contactor between the drive output and the motor, it
should be ensured the drive is in a non-output status before switch-on/switch-off of such a
contactor. Failure to comply may result in drive damage.
1.2.4 O utput F ilter
Since the drive output is PWM high frequency chopping voltage, mounting filter devices such
as an output filter and an output AC reactor between the motor and the drive shall effectively
reduce output noise, avoiding interference to other surrounding equipments.
If the length of cable between the drive and the motor exceeds 100m, an output AC reactor
is recommended to use with the purpose of preventing drive fault as a result of overcurrent
caused by excessive distributed capacitance. An output filter is optional depending on field
requirements.
Be sure not to mount phase-shifting capacitor or surge absorber at output side of the drive
since this may result in drive damage as a result of over-temperature.
1.2.5 Insulation of the motor
In view of the fact that the drive output is PWM high frequency chopping voltage accompanied
by higher harmonics, the noise, temperature rise and vibration of the motor is higher compared
with sinusoidal voltage. Particularly this debases motor insulation. Therefore, the motor should
be subjected to insulation inspection before initial use or reuse after being stored for a long
- 6 -
Emotron VSB Instruction Manual Chapter 1 Safety Precautions
period of time. The motor in regular service should also be subjected to regular insulation
inspection so as to avoid the drive damage as a result of motor insulation damage.
1.2.6 Derating
Due to the thin air in high-altitude areas, the radiating performance of the drive with forced air
cooling may degrade while the electrolyte of electrolytic capacitors is more volatile, which can
result in reduction in product life. Drive should be derated when used in an area at the altitude
above 1000 meters. It is recommended to derate 1% for every 100m when the altitude is above
1000 meters.

ATTENTION
interference to the signal wires as much as possible.
3.7 Control Terminal Wirin g
Only qualified personnel familiar with AC motor drives are allowed to implement wiring.
Failure to comply may result in equipment damage and/or personnel injury even death.
Wiring should be in strict accordance with this manual, otherwise hazard of electric
shock or equipment damage exists.
Make sure input power supply has been completely disconnected before wiring
operation. Failure to comply will result in personnel injury even death.
All wiring operations and lines should comply with EMC and national and local industrial
safety regulations and/or electrical codes. The conductor diameter should
accordance with recommendations of this manual. Otherwise, hazard of equipment
damage, fire, and/or personnel injury exists.
Screws or bolts for terminal wiring must be screwed tightly.
AC 220V signal is prohibited from connecting to other terminals than control terminals
Signal wires should to the best of possibility be away from main power lines. If this
cannot be ensured, vertical cross arrangement should be adopted, reducing EMI
