Safety Precautions
Warning: The operating potential of this board are up to 600 V
RMS
. Peak operating
potentials are up to 1350 V. Do NOT touch the board during operation. Even brief
accidental contact during operation might result in severe injury or death!
Caution: Only personnel familiar with the high voltage appliances, 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.
Warning: The evaluation or reference board contains DC bus capacitors which may
take time to discharge after removal of the main supply. Before working on the
system, wait up to 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 evaluation board DOES NOT offer proper insulation to the user. Do NOT
connect the board to the grid in any case. When supplying the AC voltage to the
board, USE ISOLATED POWER SUPPLY ONLY, and connect the earth terminal of the
board to a proper grounded point.
Caution: The heat sink and IGBT module surfaces of the evaluation or reference
board may become hot during testing. Hence, necessary precautions are required
while handling the board. Failure to comply may cause injury.
Caution: The evaluation or 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.
Warning: Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait up to five minutes after
removing power to discharge the bus capacitors. Do not attempt to service the board
until the bus capacitors have discharged to zero. Failure to do so may result in
personal injury or death.
Caution: Wiring or application errors such as supplying an incorrect or inadequate
AC supply, or excessive ambient temperatures may result in system malfunction.
Caution: The evaluation board may be shipped with packing materials that need to
be removed prior to installation. Check carefully for all the packing materials that
may interfere with the normal operation of the components. Failure to remove all
packing materials that are unnecessary for system installation may result in
overheating or abnormal operating conditions.
