Safety Precautions The following general preca utions apply when working on drives:
AT TENTION: Only those familiar with the drive
system, the products used in the system, and the
!
associated machinery should plan or implement the
installation, startup, and future maintenance of the
system. Failure to comply can r esult in persona l injury
and/or equipment damage.
AT TENTION: Verify that all sourc es of AC and DC
power are deenergized and locked out or tagged out in
accordance with the requirements of ANSI/ NFP A 70E,
Part II.
AT TENTION: The system may contain stored ener gy
devices. T o avoid the hazard of electric al shock, verif y
that all voltage on capac itors has been discharged before
attempting to service, repair , or remove a drive system
or its components. You should only attempt the
procedures in this manual if you are qualified to do so
and are familiar with solid-state control eq uipment and
the safety pr ocedures in publication NFPA 70E.
AT TENTION: When servicing any unit, do not drop
any nuts, bolts, washe rs, etc. inside the unit, as they may
cause a short circuit on power up.
AT TENTION: This drive system contains ESD
(Electrostatic Discharge) sensitive parts and
assemblies. Static contr ol precautions are requir ed
when installing, testing, or repairing this assembly.
Component damage can result if ESD control
procedures are not followed. If you are not familiar with
static control procedures, refer to Rockwell Automation
publication 8000-4. 5.2, Guardi ng Against Electr ostatic
Damage or any other applicable ESD protection
handbook.
Special Instructions Importa nt: You will need to reuse parts that are removed from the
