1.2.2 Limitations on Applications
DANGER
 This product is not designed to be used in human life-support system or machine, or be used for other special
purposes, such as passenger mobile, medical and nuclear.
 This unit has been manufactured under strict quality control. However, when it is used for important equipment, the
equipment must be provided with a safety device to prevent malfunction of this unit from resulting in serious
accident or damage.

PIM00411 1-2
1.2.3 General Precautions
DANGER
 Transportation, installation, piping, wiring, operations, maintenance and inspections must be conducted by
qualified personnel.
 During the above work, wear protective gear required for safe work (work clothes, safety band, helmet, safety
shoes, gloves and so on).
 Do not use this unit under conditions other than those specified in the catalog or delivery specifications.
 Please do not unauthorizedly modify this product by a customer. In addition, please do not disassemble it, unless
the maintenance described in this manual. There is a risk of electric shock, fire, injury.
 Please install the whole system safety device, such as emergency brake, to prevent damaging the machinery or
equipment in case that the product failures.
 Please do not operate it in an atmosphere with rubber corrosion or cutting oil directly exposed locations. In
addition, please do not use near the combustible materials.
 Please do not operate or install this product if this product lost parts or damaged.
 Do not use the product which is not listed in the specifications of this manual. There is a risk of electric shock, fire,
injury.
CAUTION
 Be sure to conduct daily inspections (described in this manual or attached documents).
 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 the
vibration of the motor pump unit from being conveyed to the whole unit. 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. And make sure the interval between
start and stop command single is more than 0.5s.
（4） 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.
（5） 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.
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
“13.7 High-pressure Safety Valve Adjustment Procedure” in this instruction manual.
（6） If it is continuously used at the highest pressure, please make sure the flowrate is under 5.0L/min.

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.
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.
