Preface
Thank you for choosing DOOCH’s high performance Q-Drive series.
The Q-Drive is a dedicated pump drive designed for variable Speed pumping system.
The Q-Drive is manufactured with high-quality components and materials and incorporate
the latest microprocessor technology available.
This manual is published for the consumers to easily operate the pump system since the
Q-drive is attached to the pump system.
Before installation and operation please peruse in this manual thoroughly.
※The information contained in this manual is subjected to change without prior notice.

ㆍDo not open cover during powered state or operation.
(Exposed high voltage terminals or charging part of DC voltage may
cause electric shock.)
ㆍDo not open cover even when power is not supplied except for
wiring or inspection work.
(When the power is turned off, charged DC voltage in charging part
of drive may cause electric shock.)
ㆍDuring wiring work or regular inspection, cut off the power and
check with tester if DC voltage is discharged after elapsed
more than 10 minutes.
(It may cause electric shock. Execute work when charging voltage
of DC part is DC 30V or less.)
ㆍDo not operate the switch or drive with wet hands.
(It may cause electric shock.)
ㆍWhen any part of drive input or cable jacket is damaged,
do not apply electricity or operate the equipment.
(It may cause electric shock.)
ㆍDo not put over stress on the input/output power cable or
signal wires of the drive with heavy object.
(It may damage on the cable jacket to cause electric shock.)
ㆍDo not install the equipment near the inflammable materials.
(Installation on or near the inflammable materials may cause fire.)
ㆍWhen drive has any fault, cut off the input power.
(If not, it may cause fire due to consequent accident.)
ㆍDo not touch the drive during powered state or several minutes
after power is turned off.
(Since drive has high temperature after operation, body contact
may cause burn.)
ㆍDo not input power for the drive with damaged product and
part even if installation is completed.
(It may cause electric shock.)
ㆍDo not leave any damageable objects from inside of drive, such
as screw, metal, water, oil, etc.
(It may cause fire.)

Cautions for Use
A. Transportation and Installation
ㆍTransport the product with correct method according to its weight.
ㆍDo not stack the products with more than specified layers.
ㆍInstall the product upon rules described on the User’s Manual.
ㆍDo not open during transportation of the product.
ㆍDo not put any heavy object on the product.
ㆍInstallation direction shall follow criteria specified on the User’s Manual.
ㆍDo not fall or give strong impact on the drive as it is a precise instrument.
ㆍDraw water completely out of the pump during winter without using for a long time.
ㆍUse the drive under the environmental conditions as mentioned below.
Installation Location Keep out of corrosive gasses, inflammable gasses,
Liquid and dust.

ㆍDo not install static condenser, radio noise filter, and so on at the output terminals of the
drive.
ㆍCheck if the power input line and motor output line are interchanged.
ㆍFaulty terminal connection may cause damage on the drive.
ㆍUse the circuit breaker.
※Do not install leakage breaker at the power input.
* If you have any problems , please contact our local agent.
C. Checkup on Initial Operation
ㆍBe sure to check setup parameters of the drive before operating it first. It may require
changing parameters according to states such as type of pump or installed system
environments.
ㆍFor terminal blocks for main power circuit and control circuit, be sure to follow connection
method and electrical specifications specified on this manual. Improper use may damage on
the drive.
ㆍBe sure to use pressure sensors and low water level sensor specified by Dooch.
D. Operation
ㆍSince it has automatic restart and recovery functions after power failure in default
and it is automatically restarted in case it is stopped due to fault or system alarm or power is
turned off during operation, be careful when power is applied initially.
ㆍDo not modify or change inside of the product without approval
ㆍDo not start or stop the drive with electronic contactor installed at the power input.
ㆍInstall EMC filters to reduce impact from electromagnetic wave in order to protect
electronic equipment being used near the drive.
ㆍInstall input reactor when input voltage is in unbalanced condition. Static condenser or
generator may be overheated and destroyed due to high frequency on power source
generated by drive.

ㆍIn case of driving 400V class motor with the drive, use the motor with reinforced
insulation or conduct suppress measure against micro-surge voltage. (Motor may
be sometimes destroyed upon deteriorated its insulation performance due to
micro-surge voltage.)
ㆍIn case of initialization of parameters, set up required parameters again before
operation. Parameter initialization changes the parameter values to factory settings.
E. Reaction on Failure and Malfunction
ㆍIn case drive is destroyed to make operation impossible, reliability of pump system
may become deteriorated. It is recommended to install additional auxiliary system in
preparation of such situations.
ㆍFor countermeasure against drive failure, refer to Chapter 7
