(Note 1)
Before shipment from the factory, the unit has been set to the maximum flow rate.
(The maximum flow rate is a theoretical value, not a guaranteed value.)
For other specifications, see the delivery specification drawing (model drawing).
The maximum pressure/flow rate can be set at values higher than the adjustable range above; for
daily use, however, be sure to observe the above pressure range/flow rate range.
This hydraulic unit incorporates a safety valve, which has been set to work at the maximum
operating pr 1.0 MPa.
However, if the surge pressure during actuator operation must be minimized, adjust the pressure
setting according to
“
Attachment: High-pressure Safety Valve Adjustment Procedure
”
.
(Note 2)
Power supply voltage fluctuation tolerance range is (10%. Even if the power supply voltage
fluctuations are within the tolerance range, when the power supply voltage fluctuates in the
positive direction, the regenerative overload (alarm stop) may occur in response, depending on
the master machine operating conditions and load conditions.

Height above the sea level
1,000 m or less
Installation place
Indoor (Be sure to fasten the unit with bolts.)
Others
Be sure to mount a no-fuse breaker (three-pole) and a ground fault interrupter.
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.
Be sure to connect the ground terminal.
(Note 3)
This unit can use only mineral hydraulic oil. (Water-containing or synthetic oil such as
water-glycol cannot be used.)
(Note 4)
When the tank oil temperature exceeds the recommended operating temperature range, pressure
pulsation may be increased, or the discharge rate may be decreased. However, such phenomena
do not indicate abnormality.
