SAFETY PRECAUTIONS (FANUC SERVO MOTOR AMPLIFIER series)
B--65245EN/02
s--19
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 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 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.
F Ensure that the combination of motor and amplifier is appropriate.
F Ensure that valid parameters are specified.
Specifying an invalid parameter for the combination of motor and amplifier may not only
prevent normal operation of the motor but also result in damage to the amplifier.
F Ensure that the amplifier an d peripheral eq u ipment are securely
connected.
Check that the magnetic contactor, circuit breaker, and other devices mounted outside the
amplifier are securely connected to each other and that those devices are securely connected to
the amplifier.
F Check that the amplifier is securely mounted in the power magnetics
cabinet.
If any clearance is left between the power magnetics cabinet and the surface on which the
amplifier is mounted, dust entering the gap may build up and prevent the normal operation of
the amplifier.
