2 Armature SCR Replacement (for 3000A 1395 Drives)
Safety Precautions The following general precautions apply when working on drives:
Special Instructions Important: You will need to reuse parts that are removed from the
drive. Place parts, in the order removed, on a clean
surface.
Important: Some washers, such as clamp and Belleville washers,
have only one correct orientation.
!
ATTENTION: 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 result in personal injury
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 requirements of ANSI/NFPA 70E,
Part II.
ATTENTION: The system may contain stored energy
devices. To avoid the hazard of electrical shock, verify
that all voltage on capacitors 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 equipment and
the safety procedures in publication NFPA 70E.
ATTENTION: When servicing any unit, do not drop
any nuts, bolts, washers, etc. inside the unit, as they may
cause a short circuit on power up.
ATTENTION: This drive system contains ESD
(Electrostatic Discharge) sensitive parts and
assemblies. Static control precautions are required
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, Guarding Against Electrostatic
Damage or any other applicable ESD protection
handbook.
