Preface
Thank you for choosing DOOCH’s high performance NSQ-Drive series.
Describing specification, installation, operation, function, and maintenance of the NSQ-Drive
series provided for the users who are familiar with and having basic experience in using a
variable frequency drive.
Be sure to understand function, performance, installation, and operation of the product by
reading through this User's Manual completely prior to your use of NSQ-Drive series that
you have purchased. In addition, you are required to have this User's Manual properly
delivered to the end-user and maintenance manager.
Safety Precautions
Remark
To prevent injury and property damage, follow these instructions. Incorrect operation
due to ignoring instructions will cause harm or damage.
The seriousness of which is indicated by the following symbols.
Even if the instructions are indicated as ‘Caution’, it can cause a serious result according to the kind
of operation and the environment.
The meaning of each symbol in this manual and on your equipment is as follows.
Warning :
This symbol indicates the possibility of death or serious injury.
Caution :
This symbol indicates the possibility of injury or damage to property.
Do not remove the cover while power is applied or the unit is in operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to high voltage terminals or
charged capacitor exposure.
Do not remove the cover except for periodic inspections or wiring, even if
the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10 minutes
after disconnecting and after checking the DC link voltage is discharged
with a meter (below DC 30V).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or
pinching.
Otherwise, you may get an electric shock.
Install the VFD on a non-flammable surface. Do not place flammable
material nearby.
Otherwise, fire could occur.
Disconnect immediately the input power if the inverter gets damaged.
Otherwise, it could result in a secondary accident and fire.
After the input power is applied or removed, the VFDwill remain hot for
a couple of minutes.
Otherwise, you may get bodily injuries such as skin-burn or damage.
Do not apply power to a damaged inverter or to the VFD with parts missing
even if the installation
Otherwise, electric shock could occur.
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign
matter into the drive.
Otherwise, fire or accident could occur.

Cautions for Use
A. Transportation and Installation
Be sure to carry VFD in a proper way suitable for its weight, or it may result in damage to the VFD.
Be sure to use heat-treated wooden crate when you adopt wooden packaging for the product.
Do not pile up VFD's above allowable limit.
Be sure to install the VFD as directed in this instruction manual.
Do not turn off the power supply to the damaged VFD.
Do not open the front cover while carrying the VFD.
Do not place the heavy material on the VFD.
The direction of installation should be observed properly as criterions specified in this manual show.
Make sure that you should not put screw, metal material, water, oil and the inflammable something else.
Keep in mind that the VFD is very vulnerable to drop from the mid air and strong shock.
Don't let the inverter exposed to rain, snow, fog, dust, etc.
Do not cover, nor block, the ventilating system having cooling fan. It may cause the VFD overheated.
Be sure to check the power is off when installing the VFD.
To prevent the risk of fire or electric shock, keep the connected wire in a sound condition.
Use the wire that meets the standard in a recommended length.
B. Wiring
A professional installer should have done the wiring and checking.
Do wiring after installing the VFD body.
Do not connect phase-leading capacitors, surge filter, radio noise filter to the output of the VFD.
Output terminals (terminals named U, V, W respectively) should be connected in a proper phase
sequence.
Make sure that there is not any short circuit terminal, wrong wiring. It may cause spurious operation
or failure.
Refrain from using a cable other than the cable shielded when you connect control circuit wiring.
Adopt the shielded wire only when wiring the control circuit. It may cause the failure of the VFD in its
operation.
Use the twisted pair shield wire for the ground terminal of the VFD
Installation Location Free of corrosive gas, inflammable gas, oil sludge and dust, etc
Temperature/Humidity -10 ~ 40℃/ Below 90% RH (Dewdrop should not be formed)
Storage Temperature -20~65℃
Elevation/Vibration Altitude 1,000m or lower / below 5.9m/sec²(=0.6g)
Ambient Atmospheric Pressure 70~106 kpa
