Make sure that the wiring is correct. In particular, check that the
output terminals U/T1, V/T2, W/T3. are NOT connected to power
and that the drive is well grounded.
Verify that no other equipment is connected to the AC motor drive
Do NOT operate the AC motor drive with humid hands.
Please check if READY LED is ON when power is applied. Check if

DC-link capacitors may still be charged to hazardous voltage
levels, even if the power has been turned off.
