Note:
Please note the following warnings regarding the hazards associated with development systems.
Table 1
Safety precautions
Warning:
The DC link potential of this board is up to 310 V
DC
. When measuring voltage
waveforms by oscilloscope, high voltage differential probes must be used. Failure to do
so may result in personal injury or death.
Warning
: The reference board contains DC bus capacitors which take time to
discharge after removal of the main supply. Before working on the drive system, wait
five 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.
Warning:
The reference board is connected to the grid input during testing. Hence,
high-voltage differential probes must be used when measuring voltage waveforms by
oscilloscope. 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.
Warning:
Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait five minutes after removing
power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Caution:
The heat sink and device surfaces of the reference board may become hot
during testing. Hence, necessary precautions are required while handling the board.
Failure to comply may cause injury.
Caution:
Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution:
The reference board contains parts and assemblies sensitive to electrostatic
discharge (ESD). Electrostatic 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 electrostatic control
procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution:
A drive that is incorrectly applied or installed can lead to component damage
or reduction in product lifetime. Wiring or application errors such as undersizing the
motor, supplying an incorrect or inadequate AC supply, or excessive ambient
temperatures may result in system malfunction.
Caution:
The reference board is shipped with packing materials that need to be
removed prior to installation. Failure to remove all packing materials that are
unnecessary for system installation may result in overheating or abnormal operating
conditions.
