3.2 Conditions of Use
Useable oil
(Note 1)
• Mineral-oil based hydraulic oil
(For the recommended brand, see our “DAIKIN OIL HYDRAULIC EQUIPMENT
Catalog (HK196)”.)
• Viscosity grade: ISO VG 32 to 68
• Dynamic viscosity range: 20 to 88 mm
2
/s (recommended values), 15 to 400
mm
2
/s (usable range)
• Contamination: Within NAS class 10, water content 0.1%vol max.
• Tank oil temperature range: 15 to 50°C (recommended values), 0 to 60°C
(usable range)
(Note 3)
Input power supply
(Note 2)
• AC 3-phase, 200/200/220 V, 50/60/60 Hz (Permissible voltage fluctuation:
±10%)
Discharge port Rubber hose connection
Operating ambient
temperature
0 to 40 °C
Storage ambient
temperature

Operating altitude 1,000 m maximum
Installation site Indoors (Be sure to fix with bolts, etc.)
Other
• Be sure to install no-fuse breakers at all poles (3 poles or 2 poles) at the main
circuit power supply side (primary side).
• Wire electrical connections so as to satisfy JIS B 9960-1 (European standard
EN60204-1).
• Turning the power ON/OFF within a short time will significantly shorten the life
of the controller. If operation is to be repeatedly started/stopped with an
interval of shorter than 8 minutes, use start/stop signals. Note, however, that
they must be used with an interval of at least 0.5 seconds between the stop
command and restarting.
• Be sure to ground ground terminals in accordance with the law in the country
concerned. Make a direct connection without going through a circuit breaker.
Note 1: Hydraulic oil must be the mineral-base oil type (e.g. water-glycol can’t be used).
Note 2: Note that if there is fluctuation on the plus side even if it is within the tolerance, an overvoltage
alarm that stops operation may occur at the response, depending on the operating conditions of
the main machine and the load conditions. Note that if there is fluctuation on the minus side even
within the permissible fluctuation of the power supply voltage, it can adversely affect the output
characteristics.
Note 3: When using the product outside the recommended operating temperature range, the pressure
pulsations may become large and the discharge rate may decrease, but this is not abnormal.
