2. Multiple AC Motor Drives Wiring
The following are important points for your attention.
A. Refer to the diagram below to wire the unit.
1) Follow the motor drive specifications to choose the appropriate non-fuse breaker (NFB) and
the magnetic contactor (MC).
2) Connect an input reactor to a motor drive following the instructions in the user manual. A 3%
AC input reactor is recommended. Connect an input reactor to the motor drive with the shortest
distance possible.
3) See Section 5-3 to choose an appropriate fuse.
4) The maximum cable length between a REG2000 and an EMI filter cannot be more than 10 m.
Remove the RFI jumper before you install an EMI filter.
5) DO NOT install any other Power Regenerative Unit on the common DC BUS.
6) The maximum cable length between DC+ and DC- cannot be more than 5 m. Twisted pair is
recommended.
7) Follow the wiring diagram to install the DC reactor (standard accessory) to reduce the
electromagnetic interference (EMI) and to increase the work efficiency.
8) Follow the specifications in Section 5-4 to choose an appropriate EMI filter to avoid strong
electromagnetic interference (EMI).
B. Make sure that your AC motor drives can operate on a common DC BUS at first. Verify that the
AC motor drives have the correct specifications.
C. In order to choose the proper Power Regenerative Unit, first confirm the maximum regenerative
energy while all AC motor drives work at the same time.
D. For one-to-many installation, install a fuse (Fuse A/B/C…, as shown in the diagram below) at the
DC input side of every drive. Calculate and select a suitable fuse for every drive: Fuse type =
(Rated input current of the drive) x 2.5.
