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.
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.
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.
