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.
Touching electrical parts may be fatal ñ even after equipment has
been disconnected from AC line. To be sure that capacitors have
fully discharged, wait 14 minutes after power has been removed
before touching any internal component.

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 BACLink portal 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.
