DANGER
!
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.
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.
WARNING
!
Warnings Against Unintended
Start
1. While the drive is connected to the AC line, the motor
can be brought to a stop by means of external switch
closures, serial bus commands or references. If personal
safety considerations make it necessary to ensure that
no unintended start occurs, these stops are not sufficient.
2. During programming of parameters, the motor may start.
Be certain that no one is in the area of the motor or
driven equipment when changing parameters.
3. A motor that has been stopped may start unexpectedly
if faults occur in the electronics of the drive, or if an
overload, a fault in the supply AC line or a fault in the
motor connection or other fault clears.
4. If the “Local/Hand” key is activated, the motor can only
be brought to a stop by means of the “Stop/Off” key or
an external safety interlock.
CAUTION
!
Electronic components of LonWorks option card
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.
Touching electrical parts may be fatal, even after equipment has
been disconnected from AC line. To be sure that capacitors have
fully discharged, wait 14 minutes for 208 V and 460 V units and
30minutes for 600 V units over 25 HP after power has been
removed before touching any internal component.
