Delta HES Series User Manual page 3

Never connect AC power to the output terminals U/T1, V/T2, and W/T3 of Hybrid
Servo Controller.
Please do not conduct stress test on the internal components of Hybrid Servo
Controller, for the semiconductor devices therein may be damaged by high-voltage
breakdown.
Even when the servo oil pump is off, the main loop terminal of Hybrid Servo
Controller can still be loaded with high voltage that can be seriously dangerous.
Only qualified professional electrical engineers can conduct tasks of installation,
wiring, and maintenance of Hybrid Servo Controller。
When Hybrid Servo Controller uses external terminals as its run command sources,
the servo oil pump may start running immediately after the power is connected,
which may be dangerous with any personnel present.
Please choose a safe area to install Hybrid Energy System, where there is no high
temperature, direct sunlight, moisture, and water dripping and splash.
Please follow the instructions when installing Hybrid Energy System. Any
unapproved operation environment may lead to fire, gas explosion, and
electroshock.
When the wiring between the hybrid controller and the hybrid servo motor is too
long, it may compromise the interlayer insulation of the motor. Please install a
reactor between them (please refer to Appendix A) to avoid burning of the hybrid
servo motor from damaged insulation.
The voltage rating of the power supply of Hybrid Servo Controller 230 series cannot
be higher than 240V (no higher than 480V for 460 series) and the associated
current cannot exceed 5000A RMS ( no higher than 10000A RMS for models with
40HP (30kW))
