The motor cable terminals of the drive are at a dangerously high voltage when mains
power is applied, regardless of motor operation.

There can be dangerous voltages inside the drive from external control circuits even
when the drive mains power is shut off.

Exercise appropriate care when working on the unit.

These warnings are intended for all who work on the drive. Ignoring the instructions
can cause physical injury or death, or damage the equipment.

For complete safety instructions see the drive manuals.
