Safety
WARNING
HIGH VOLTAGE!
Frequency converters contain high voltage when connected
to AC mains input power. Installation, start up, and
maintenance should be performed by qualified personnel
only. Failure to perform installation, start up, and
maintenance by qualified personnel could result in death or
serious injury.
High Voltage
Frequency converts are connected to hazardous mains
voltages. Extreme care should be taken to protect against
shock. Only trained personnel familiar with electronic
equipment should install, start, or maintain this equipment.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains, the
motor may start at any time. The frequency converter, motor,
and any driven equipment must be in operational readiness.
Failure to be in operational readiness when the frequency
converter is connected to AC mains could result in death,
serious injury, equipment, or property damage.
Unintended Start
When the frequency converter is connected to the AC mains,
the motor may be started by means of an external switch, a
serial bus command, an input reference signal, or a cleared
fault condition. Use appropriate cautions to guard against an
unintended start.
WARNING
DISCHARGE TIME!
Frequency converters contain DC link capacitors that can
remain charged even when AC mains is disconnected. To
avoid electrical hazards, remove AC mains from the
frequency converter before doing any service or repair and
wait the amount of time specified in Table 1
.1
. Failure to wait
the specified time after power has been removed prior to
doing service or repair on the unit could result in death or
serious injury.
Voltage (V) Minimum waiting time (minutes)
415
200 - 240 0.25 - 3.7 kW 5.5 - 37 kW
380 - 480 0.25 - 7.5 kW 11 - 75 kW
525 - 600 0.75 - 7.5 kW 11 - 75 kW
525 - 690 n/a 11 - 75 kW
High voltage may be present even when the warning LEDs are off!

Symbols
The following symbols are used in this manual.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices.
CAUTION
Indicates a situation that may result in equipment or
property-damage-only accidents.
NOTE
Indicates highlighted information that should be regarded
with attention to avoid mistakes or operate equipment at
less than optimal performance.
