Please follow the power rating listed in the
user's manual (chapter 1)
A larger current may be generated when the
power is turned on. Please refer to Appendix
B-1 to select suitable non-fused switch or fuse.
Turning on/off the side electromagnetic
contactor can start/stop the hybrid servo
controller. However, frequent switching may
lead to malfunction. It is advised not to turn
on/off the hybrid servo controller for more
than 1 time/hour.
When the output capacity exceeds 1000kVA,
it is recommended to add an AC reactor to
improve the power factor, with the wiring
distance within 10m. Please refer to
Appendix B-2 for details.
This is to reduce the radiation interference,
especially in places with audio devices.
It can also reduce the interferences at the
input and output sides. Please refer to
appendix B-2 for details. The effective
range is from AM band to 10MHz.
It can be used to reduce electromagnetic
interference. Please refer to Appendix B-5
for details.
