WARNING
Danger due to high voltages after a safety shutdown
In spite of a safety shutdown function, the drive may still be operational or high voltages may
still be present.
Residual voltages can result in death, severe injury or significant material damage. The
"Safety shutdown" function can neither ensure that the drive stops immediately nor can it
ensure that residual voltages do not still exist at the output terminals and within the unit.
● Make sure that the drive no longer rotates and that there are no high voltages present.
