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 converters 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 the frequency converter is
not powered. To avoid electrical hazards, disconnect AC
mains, any permanent magnet type motors, and any
remote DC-link power supplies, including battery
backups, UPS and DC-link connections to other
frequency converters. Wait for the capacitors to fully
discharge before performing any service or repair work.
The amount of wait time is listed in the Discharge Time
table. Failure to wait the specified time after power has
been removed before doing service or repair could result
in death or serious injury.
Voltage [V] Minimum waiting time [minutes]
4 7 15
200-240 1.1-3.7 kW 5.5-45 kW
380-480 1.1-7.5 kW 11-90 kW
525-600 1.1-7.5 kW 11-90 kW
525-690 1.1-7.5 kW 11-90 kW
High voltage may be present even when the warning LED
indicator lights are off.

Indicates a situation that could result in equipment
or property-damage-only accidents.
NOTE
Indicates highlighted information to regard with
attention to avoid mistakes or operate equipment at less
than optimal performance.
Approvals
The frequency converter complies with UL508C thermal
memory retention requirements. For more information
refer to 2.4.5 Motor Thermal Protection.
NOTE
Imposed limitations on the output frequency
(due to export control regulations):
From software version 3.92 the output frequency of the
frequency converter is limited to 590 Hz.
