WARNING : Always perform applicable lock-out/tag-out procedures (either
general or site-specific) before performing any maintenance or trouble-
shooting on the system.
WARNING : To avoid potentially lethal levels of both AC and DC voltages,
do not remove the cover to access the Input/Output section of the Inverter
while the Inverter is energized.
WARNING : Potentially hazardous voltages will remain in the cells until the
capacitors are able to de-energize. Wait at least 30 minutes after main
power is removed for the stored voltages to dissipate if removing the In-
verter Cell or Input/Output section covers. Do not rely solely on the volt-
age values displayed on the HMI Meter Values screen to determine if it is
safe to remove the covers on the Inverter Cell and Input/Output sections.
WARNING : The Control section contains 240V control power when active.
The Control section does not contain medium voltage levels supplied from
the mains, and can be carefully accessed by qualified personnel while me-
dium voltage from the AC mains is applied to the system.
WARNING : Replace all devices, doors, and covers before applying power
to this equipment.
CAUTION : The contacts on the supplied shunt trip relay must be con-
nected to the feed breaker. The shunt trip is used to protect the drive and
motor from damage in the event of certain fault conditions.
CAUTION : Special care must be taken with the cover over the Control
section and all panels. A ground wire is attached to the inside of that cover
that ties it to ground potential. It is important that the connection integrity
of this wire be maintained to avoid compromising the immunity of the In-
verter to Electromagnetic Interference (EMI.)
CAUTION : Always be aware of electrostatic discharge (ESD) when work-
ing near or touching components inside the drive. Handling of components
sensitive to ESD should be done by qualified personnel only, familiar with
ESD mitigation techniques.
CAUTION : Parameter settings and adjustments should be performed by
those familiar with VFD and motor operation characteristics. It is not rec-
ommended for users unfamiliar with these concepts.
