<1> Remove the jumper when installing a DC link choke. Models CIMR-LU20085 through 20415, 40045
through 40605, and 50032 through 50200 come with a built-in DC link choke.
<2> Set L8-55 to 0 to disable the protection function of the built-in braking transistor of the drive when using an
optional regenerative converter or dynamic braking option.
<3> Set up a thermal relay sequence to disconnect drive main power in the event of an overheat condition on the
dynamic braking option.
<4> Self-cooling motors do not require the same wiring necessary for motors with separate cooling fans.

If running from a 400 V power
supply or 600 V power supply, a
step-down transformer is needed
to reduce the voltage to 200 V.
