General Precautions
!
ATTENTION: This drive contains ESD (Electrostatic Discharge)
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, refer to Allen-Bradley publication 8000-4.5.2,
“Guarding Against Electrostatic Damage” or any other applicable
ESD protection handbook.
!
ATTENTION: An incorrectly applied or installed drive can
result in component damage or a reduction in product life. Wiring
or application errors, such as, undersizing the motor, 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: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing
any work on the drive. After removing power to the drive, wait 5
minutes for the bus capacitors to discharge. Refer to the:
•
LPM20 Liquid-Cooled Adjustable Frequency AC Drive
Installation Manual (Publication No. 20N-IN001…),
Figure 4.2, and measure the DC bus voltage at the locations
shown. The voltage must be zero.
•
PowerFlex 700L Liquid-Cooled Adjustable Frequency AC
Drive User Manual (Publication No. 20L-UM001…), and
measure the DC bus voltage at the DC POSITIVE and DC
NEGATIVE test point sockets located on the front of the power
module. The voltage must be zero.
!
ATTENTION: Risk of injury or equipment damage exists. DPI
host products must not be directly connected together via 1202
cables. Unpredictable behavior can result if two or more devices
are connected in this manner.
