• Make sure that MC3 and MC2 are mechanically interlocked. Doing so may cause an inverter dam-
age.
Additional Information
• For FWY, RVY, and CSY, use low-voltage relays according to your application.
• If an overcurrent trip occurs during frequency matching, increase the Restart Standby Time
(b003).
• The inverter can be set up to restart automatically at power-on. In this case, the terminal CS
is not required. For details, refer to
5-8-2 Restart after Resetting
on page 5-45.
