Hazards, Warnings and Guidelines
Hazards and
Warnings Read the following precautions very carefully to ensur e the safety of personnel at
your site. Failure to comply will result in death, se rious injury or equipment damage.
DANGER!
ELECTRIC SHOCK HAZARDS
lDuring operation, keep all covers and cabinet do or s closed.
lDo not open the drives; depending on degree of enclosure protection, the
drives may have exposed components.
lControl and power connections on the drive may be energized even if the
motor is not rotating.
lNever attempt to disconnect the electrical connections to the drive with power
applied. Failure to comply may result in arcing at the contacts.
lWait 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.
lCheck 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.
Failure to follow any one of these instructions will result in death, serious
injury or equipment damage.
