•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).
•If operation is to be repeatedly started/stopped with an interval of shorter than 5 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.
(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.
