Chapter 2 Installation and Wiring
General Precautions
In addition to the precautions listed throughout this manual, the following
statements, which are general to the system, must be read and understood.
Precautions for Bulletin
280E/281E Applications
Precautions for Bulletin 284E
Applications
ATTENTION: The controller contains ESD (electrostatic discharge) sensitive
parts and assemblies. Static control precautions are required when installing,
testing, servicing, or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with static
control procedures, refer to Publication 8000-4.5.2
, Guarding against
Electrostatic Discharge, or any other applicable ESD protection handbooks.
ATTENTION: An incorrectly applied or installed controller can damage
components or reduce 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 personnel familiar with the controller and associated
machinery should plan or implement the installation, startup, and
subsequent maintenance of the system. Failure to do this may result in
personal injury and/or equipment damage.
ATTENTION: To prevent electrical shock, open the disconnect switch prior to
connecting and disconnecting cables. Risk of shock – environment rating
may not be maintained with open receptacles.
WARNING: The drive contains high voltage capacitors which take time to
discharge after removal of mains supply. Before working on a drive, ensure
isolation of mains supply from line inputs (R, S, T [L1, L2, L3]). Wait three
minutes for capacitors to discharge to safe voltage levels. Failure to do so may
result in personal injury or death. Darkened display LEDs are not an indication
that capacitors have discharged to safe voltage levels. Risk of shock –
environment rating may not be maintained with open receptacles.
ATTENTION: Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery should plan or implement the installation,
startup, and subsequent maintenance of the system. Failure to do this may
result in personal injury and/or equipment damage.
