o The motor's direction of rotation might not be controlled.
o The motor speed might not be controlled.
o The motor might be energized.
• An inverter is a component within an inverter system that may
influence its operation or effects under a fault condition. Consideration
must be given to:
o Stored energy
o Supply disconnects
o Sequencing logic
