<1> Remove the jumper when installing a DC link choke. Models CIMR-LU2A0085 through 2A0415, 4A0045
through 4A0605, and 5A0032 through 5A0200 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.

Wiring sequence should shut off
power to the drive when a fault
output is triggered.
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.
