General Precautions
!
ATTENTION: The Diode Bus Supply contains electrostatic
discharge (ESD) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with
static control procedures, see Guarding Against Electrostatic
Damage, publication
8000-4.5.2 , or any other applicable ESD
protection handbook.
!
ATTENTION: An incorrectly applied or installed Diode Bus
Supply can result in component damage or a reduction in product
life. Wiring or application errors, such as incorrect or inadequate
AC supply, or excessive ambient temperatures may result in
malfunction of the system.
!
ATTENTION: Only qualified personnel familiar with adjustable
frequency AC drives and associated machinery should plan or
implement the installation, start-up and subsequent maintenance of
the system. Failure to comply may result in personal injury and/or
equipment damage.
!
ATTENTION: Only connect Rockwell Automation common DC
bus drives with built-in precharge circuitry to the common DC bus
output terminals of the Diode Bus Supply within the load rating
guidelines. See
Specific Drive Information earlier in this Preface
for available drives.
!
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the DC bus terminals (which are connected to the DC
bus capacitors of the Inverter) has discharged before performing
any work on the Diode Bus Supply. Measure the DC bus voltage at
the +DC and -DC output terminals. The voltage must be zero.
!
ATTENTION: National Codes and standards (NEC, VDE, BSI,
and so forth) and local codes outline provisions for safely
installing electrical equipment. Installation must comply with
specifications regarding wire types, conductor sizes, branch circuit
protection, and disconnect devices. Failure to do so may result in
personal injury and/or equipment damage.
