Equipment Hazard!
Rotating shafts and electrical equipment
can be hazardous. Therefore, it is strongly
recommended that all electrical work
conform to National Electrical Code (NEC)
and all local regulations. Installation, start-
up and maintenance should be performed
only by qualified personnel. Failure to
follow the NEC or local regulations could
result in death or serious injury.
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servicing
drives and electronic controls, there will be exposed
components at or above line potential. Extreme care
should be taken to protect against shock. Stand on an
insulating pad and make it a habit to use only one hand
when checking components. Always work with another
person in case of an emergency. Disconnect power
whenever possible to check controls or to perform
maintenance. Be sure equipment is properly grounded.
Wear safety glasses whenever working on electric
control or rotating equipment.
Hazardous Voltage!
Touching electrical parts may be fatal, even after equipment has been
disconnected from the AC input line. To be sure that capacitors have fully
discharged, wait 14 minutes for 208 V and 480 V units and 30 minutes for 600 V
units over 25 hp after power has been removed before touching any internal
component. Failure to wait for capacitors to fully discharge before touching
internal components could result in death or serious injury.
Unintended Start!
In Auto Mode, a start signal via digital
inputs may cause drive to start at any time.
The drive, motor, and any driven equipment
must be in operational readiness. Failure
to be in operational readiness in Auto Mode
could result in death, serious injury, or
equipment or property damage.
CAUTION
Electrostatic Discharge!
Electronic circuit card components are
sensitive to electrostatic discharge (ESD).
ESD can reduce performance or destroy
sensitive electronic components. Follow
proper ESD procedures during installation
or servicing to prevent damage.
