 Do not apply external force to this unit. (Do not step on, or pound on this unit.) Otherwise, you may suffer from
injury, or the unit may be damaged.
1.3 Precautions for Use

（1） In this hydraulic unit, the motor pump unit is equipped with vibration suppressing rubber to prevent
vibration of the motor pump unit from being conveyed to the whole unit. For this purpose, the discharge
pipe provides a large degree of freedom. Therefore, when connecting the discharge pipe, be careful that the
discharge pipe will not touch the cover even if the pipe shakes with reaction force of the hose.
The piping to the unit should be connected with a hose, so that vibration of the motor pump unit will not be
conveyed to the machine.
（2） This hydraulic unit is equipped with an AC fan for cooling of hydraulic oil and motor.
To ensure spaces for air intake and exhaust, do not place an obstacle at 10 cm or shorter distance from the
fan motor air intake and exhaust planes.
（3） Frequently turning ON/OFF the power supply causes the controller service life to be remarkably shortened.
If you start and stop the hydraulic unit repeatedly by turning ON/OFF the power supply at intervals of 8
minutes or less, use the “start/stop” function using the start/stop signal.

（4） If you use this product in a hydraulic circuit fitted with in-line check valve on the pump discharge side, it
will not be able to control the pressure reducing of the load side. In addition, if the hydraulic circuit has
accumulators, please use check valve to prevent reverse flow to the pump side from the accumulator circuit.
When the power supply is turned OFF, because of the reverse flow, the motor will become a generator
which may damage the controller.
If load is applied to the pump when the power is turned on, there is a possibility that the motor does not
start properly. Please do not apply load to the pump for 5 seconds from power-on.

（5） This hydraulic unit uses an IPM motor, which generates counter-electromotive force during changeover
(regenerative operation). If the motor is frequently turned ON/OFF in the operating condition that easily
generate counter-electromotive force (a large load volume causes a large load reaction force accordingly),
it causes regenerative overload, resulting in unit stop.
（6） This hydraulic unit is equipped with a safety valve.This safety valve has been set to a specified pressure
before shipment. However, the set pressure of the safety valve may decrease while the machine is
repeatedly used for a long period, or due to contaminants in the hydraulic oil.


PIM00424 1-3
If this unit is continuously used in the state that the safety valve is actuated, it may output an alarm due to a
temperature rise and so on.In this case, re-adjust the high pressure safety valve pressure setting according to
“13.8 High-pressure Safety Valve Adjustment Procedure” in this instruction manual.

（7） If it is continuously used at the highest pressure, please follow the flowrate in the table below.

■Continuous flow rate at the highest pressure
Product Type Flowrate
SUT00S8007-30
SUT10S8007-30 19L/min or less

1.4 Using it safely
This manual and other annexes should be read before installation, operation and maintenance. After being familiar
with all of the precautions and safety information of this equipment, please correctly use it.
1.4.1 Installation and wiring
DANGER
● Only the qualified personnel can do the wiring work. There is a risk of electrical shock or fire.
● Wiring worker should take safety measures, such as wearing long sleeves and gloves, for injury prevention.
● Wiring worker should take safety measures , such as wearing long sleeves and gloves, to prevent electric
shock or fire due to static electricity.
● Please wire after completing the installation. There is a risk of electrical shock or fire.
● Please wire after turning OFF the input power. There is a risk of electrical shock.
● If there is necessary to wire again after the power is turning ON, please make sure the motor is stopped and
the input power is turned OFF 5 minutes or more. There is a risk of electrical shock.
● Connect the no-fuse breaker and electric leakage breaker that conforms to EN60947-2 to the power supply
line. There is a risk of electrical shock or fire. Please refer to the "9.2 Breaker Installation " for breaker
capacity information.
● Please connect the ground terminal by the D class grounding method (formerly Class 3 grounding) . There is a
risk of electrical shock or fire.
● Please prevent the screws, conductive materials (for example metal piece), wood chips, flammable matter (oil)
entering the internal controller. There is a risk of electric shock, fire, or accident.
● Please do not use it near water or flammable materials, or in corrosive atmosphere or atmosphere of
inflammable gas. There is a risk of electric shock or fire.
● Do not scratch or apply force to the harness, and do not place heavy objects on the harness, pinch or bend it.
There is a risk of electric shock or damage.
● Please use the eye bolt to move the product. There is a danger of falling, if lift it by pump piping.
● Please do not operate or install this product if this product lost parts or damaged.There is a risk of accident.
● There is an orifice check valve in the discharge line in this hydraulic unit. It is important to set a pressure
release circuit, if the high response performance, such as pressure relief, is required.In addition, if the volume
of the load side is large, at the time of shutdown, the fluid sound may be generated from the orifice portion.

switching point of the solenoid valve, it is possible that the instability phenomenon may occur. In this case,
please change the settings of flow rate (qH) or pressure (PL) lower than the switching point (refer to page
[P00] ~ [P03]). It can also be stabilized by adjusting the width of the dead zone which is near the switching
point (refer to page 12-3 [P16] ~ [P17]).

Chapter 2 Features and Structure

2.1Energy-saving
By using the highly efficient IPM motor driving system that DAIKIN originally developed, this hydraulic
unit remarkably improved the energy efficiency of the motor.
Two fixed displacement pumps (high-pressure small-capacity, low-pressure high-capacity) are adopted in
this double-pump specification. In this system, single/confluence mode can be automatically switched
according to load pressure. When the flow rate is necessary, the high-pressure small-capacity pump and
the low-pressure high-capacity pump are joined together to rotate at a high speed. When the flow rate is
not necessary (for example, pressure holding state), only the high-pressure small-capacity pumprotates
at a low speed. In this way, significant energy saving effect is achieved.

2.2Multi-stage speed control/Multi-stage pressure control, and shockless control functions
◆ The Super Unit enables multi-stage pressure control/flow rate control by selecting 16 patterns of P-Q
characteristics that have been registered in the controller from the master machine.
◆The Super Unit enables shockless control by setting/adjusting the rising/falling time at changes of the P-Q
characteristics.
2.3Simplification of the system
◆ The functions that have been controlled by valves in a conventional system can be controlled by pumps.
Therefore, when this system is used for high-speed/low-speed switching (for a press etc.) and multi-stage
pressure control applications, the system configuration can be simplified, and costs can be reduced.

CAUTION
 When shipped from the factory, the maximum flow rate was set. [Low pressure (confluence) side flow rate
setting value]
 Though the pressure and flow rate can be set beyond the adjustment range, please be sure to use it within the
pressure range and flow rate range.
 The high-pressure safety valve is installed in this hydraulic unit, and pressure is set as shown in the following
table.Product type High pressure safety valve setting pressure

Others
・Be sure to mount a no-fuse breaker (three-pole) in main power supply circuit.
・Make sure that the electric wiring conforms to European Norm EN60204-1.
・If you frequently turn ON/OFF the power supply for this unit, the controller service life
will be remarkably deteriorated. If you intend to start and stop the unit at intervals of
eight minutes or less, use the start/stop signal function of this unit. However, if the start-
stop function is being used, please make sure the interval time is upto one minute or
more.
・Be sure to connect the ground terminal.

responding the regenerative overload alarm raises and the unit stops depending on the main
machine’s operating conditions and the load conditions. If the change is – side, the output
characteristics may become low.
（Note 3） If its operating temperature beyond the recommended temperature range, the pressure
pulsation may increase, the discharge flow rate may reduce, but it is not a malfunction.
