Wiring Precautions
!
1. Always follow all local, regional, national and international electrical
codes! In case of conflicts between regulations and this instruction
manual please contact the factory.
!
2. Connect ground signals first and remove them last when installing or
removing equipment.
!
3. Arrange the servo amplifier, noise filters and motion controller as closely
to each other as possible to minimize signal length and reduce effects of
noise.
!
4. Install surge suppression circuits on relays, electromagnetic contactors,
brake solenoids and other inductive loads.
!
5. Do not pass the bus power and circuits and control signals in the same
conduit or bind them together.
!

install noise filters.
