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.
