<1> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt
power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart itself. The default setting for L5-02
is 0 (fault output not active during restart attempt).
<2> Self-cooling motors do not require wiring that would be necessary with motors using a cooling fan.
<3> Use a three-phase power supply with a voltage of 380 to 480 V for drive models 40011 to 40414 (built-in EMC filter) and 40477 to
40590 (with stand-alone EMC filter).

Wiring sequence should shut off
power to the drive when a fault
output is triggered.
If running from a 400 V power supply,
a step-down transformer is needed to
reduce the voltage to 200 V.
