Read the following precautions very carefully to ensure the safety of personnel at 
your site. Failure to comply will result in death, serious injury or equipment damage.

l

During operation, keep all covers and cabinet doors closed.

l

Do not open the drives; depending on degree of enclosure protection, the 
drives may have exposed components.

l

Control and power connections on the drive may be energized even if the 
motor is not rotating.

l

Never attempt to disconnect the electrical connections to the drive with power 
applied. Failure to comply may result in arcing at the contacts.

l

Wait at least five minutes after disconnecting the drive from the mains supply 
voltage before touching energized sections of the equipment (for example, 
contacts) or disconnecting electrical connections. Capacitors can still have 
dangerous voltages present up to five minutes after switching off the supply 
voltages. To ensure safety, measure the voltage in the DC Link circuit and wait 
until it has fallen below 40V before proceeding.

l

Check to ensure all energized connecting elements are protected from 
accidental contact. Lethal voltages up to 900V can be present. Never 
disconnect any electrical connections to the drive with power applied; 
capacitors can retain residual and dangerous voltage levels for up to five 
minutes after switching off the supply power.
