Safety Precautions The following general precautions apply to Bulletin 2364 products
and their respective drive systems:
ATTENTION: Only those familiar with th e 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 compl y can res ult i n person al inj ury
and/or equipment damage.
ATTENTION: Verify that all sources of AC and DC
power are deenergized and locked out or tagged out in
accordance with the re quireme nts of ANSI/ NFPA 70E,
Part II.
ATTENTION: The system may conta in stored ener gy

that all voltage on capacitors has been discharged bef ore
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-stat e contro l equipment and
the safety procedures in publication NFPA 70E.
ATTENTION: When servicing any unit, do not drop
any nuts, bolts, washers, etc . inside t he unit as they may
cause a short circuit on power up . Dropped i tems mu st
be found and removed before you apply power.
ATTENTION: This drive system contains ESD
(Electrostatic Disc harge) sensitive parts and assemblie s.
Static control precautions are required when installing,
testing, or repair ing 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,
Guarding Against Electrostatic Damage or any other
applicable ESD protection handbook.
Special Instructions The following special instructions apply to Bulletin 2364 products
and their respective drive systems:
