1 DJ Series ew DIPK omenclature Features DJ Low noise The tank contains the pump and motor inside and functions itself as noise insulation panels to trap noise internally. Low oil temperature rise hollow tank with a large heat exchange area and forced cooling of the tank's internal panels and the pump surfaces with a motor cooling fan suppresses fluid temperature rise. ompact design Reduced installation space with compact design Model o.

2 Paint color Tank: Ivory white (Munsell code Y7./) Pump: lack Handling Hydraulic fluid, ambient environment Use a petroleum-based hydraulic fluid equivalent to ISO VG to 46. Use of hydraulic fluids other than the petroleum-based type (e.g. hydrous/synthetic) is prohibited. Operate the unit in an environment where both the following conditions are satisfied: viscosity range from to 400 mm /s {cst} and oil temperature from 0 to 60. e sure to maintain the water content in the hydraulic fluid at 0.% maximum by volume. ontamination of the hydraulic fluid causes device trouble and reduces the service life, so pay due attention to controlling contamination and ensure that it goes no higher than S contamination class 0. Use the unit indoors under the following conditions. mbient temperature: 0 to, mbient humidity: 0 to 90%RH (with no condensation) t start Fill the pump case with hydraulic fluid through the filler port before starting trial operation, after replacing the pump, or after stopping the unit for months or longer. Use the same hydraulic fluid as for the hydraulic circuit. DJ8 DJ9 Pump case filling volume cm fter checking that all hydraulic circuits and electrical circuits are ready for operation, set the hydraulic circuit at the load side in the no-load status or connect an unloading circuit before starting the pump. When the pump is driven for the first time, turn the power switch to the motor on and off a few times to let the air out of the piping and then run it continuously at full speed. oise may be observed until the air has been completely removed but this is not abnormal. Electric wiring onnect the power cable matching the phases at the pump motor and power supply sides as shown below. Motor side U V W R S T Power supply side heck that the pressure at the delivery side rises at the pressure gauge. If wires are connected with the wrong phase order, the motor and pump rotate in the reverse direction and no fluid is discharged. If fluid is not discharged within minutes after turning the power on, the phase order may be incorrect. In this case, switch the wires for two phases among the three. e sure to connect the ground terminal. Install a no-fuse breaker and an earth leakage breaker on the main power supply. The electrical ratings are as shown in the table below. These are premium efficiency products and therefore they tend to have a higher current value than products with the previous design. Pay attention to the design of the power distribution when replacing products of the previous design. <Motor rating table (rated current)> Permissible voltage fluctuation: ±0% Motor capacity Output kw (umber of poles: 4) 00 V (0 Hz) Rated current () 00 V 0 V 00 V (0 Hz) Starting current () 00 V 0 V DJ (-L) DJ 8--0 (-L) DJ9--0 (-L) ir intake/exhaust Do not place any obstacles to motor cooling fan air intake and exhaust within a distance of 00 mm from intake and exhaust vent of the motor cooling fan. Install the unit at a location with good air flow so that heated air can be vented. Transportation Use eye bolts for hoisting to transport the unit. Installation The unit is a stationary type. Fix it with bolts on a level location that is free of vibration. -8
