Hazards, Warnings and Guidelines
Hazards and
Warnings 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.
DANGER!
ELECTRIC SHOCK HAZARDS
l
During operation, keep all covers and cabinet doors closed.
l
Do not open the servo drives; depending on degree of enclosure protection,
the servo 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 servo drive with
power applied. Failure to comply may result in arcing at the contacts.
l
Wait at least five minutes after disconnecting the servo 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 servo 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.
