1.1.1 Safety
WARNING
HIGH VOLTAGE!
Adjustable frequency drives contain high voltage when
connected to AC line 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
Adjustable frequency drives are connected to hazardous
AC line voltage. 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 adjustable frequency drive is connected to AC
line power, the motor may start at any time. The
adjustable frequency drive, motor, and any driven
equipment must be in operational readiness. Failure to be
in operational readiness when the adjustable frequency
drive is connected to AC line power could result in death,
serious injury, equipment, or property damage.
Unintended Start
When the adjustable frequency drive is connected to the
AC line power, 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
precautions to guard against an unintended start.
WARNING
DISCHARGE TIME!
Adjustable frequency drives contain DC link capacitors that
can remain charged even when AC line power is discon-
nected. To avoid electrical hazards, remove AC line power
from the adjustable frequency drive before doing any
service or repair and wait the amount of time specified in
. 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.
