SAFETY PRECAUTIONS
B–65192EN/02
s–4
CAUTION
F Do not step or sit on the amplifier.
Also, do not stack unpacked amplifiers on top of each other.
F Use the amplifier in an appropriate environment.
See the allowable ambient temperatures and other requirements, given in the corresponding
descriptions.
F Protect the amplifier from corrosive or conductive mist or drops of water.
Use a filter if necessary.
F Protect the amplifier from impact.
Do not place anything on the amplifier.
F Do not disassemble the amplifier.
F Do not block the air inlet to the radiator.
A deposit of coolant, oil mist, or chips on the air inlet will result in a reduction in the cooling
efficiency. In some cases, the required efficiency cannot be achieved. The deposit may also lead
to a reduction in the useful life of the semiconductors. Especially, when outside air is drawn in,
mount filters on both the air inlet and outlet. These filters must be replaced regularly. So, an
easy–to–replace type of filter should be used.
F Connect the power supply lines and power lines to the appropriate
terminals.
F Connect the signal lines to the appropriate connectors.
F Ensure that the cables used for the power supply lines and power lines are
of the appropriate diameter and temperature ratings.
F Do not apply an excessively large force to plastic parts.
If a plastic section breaks, it may cause internal damage, thus interfering with normal operation.
The edge of a broken section is likely to be sharp and, therefore, presents a risk of injury.
F Before connecting the power supply wiring, check the supply voltage.
Check that the supply voltage is within the range specified in this manual, then connect the power
supply lines.
