Special Precautions 9 - Panasonic AAD03011 Instruction Manual

To meet requirements of European standard directive, please refer to precautions
on Page 98.
Use the inverter only within tolerable ambient temperature range.(-10
Because the life of the inverter is greatly affected by ambient temperature,
use it within tolerable temperature range. Also, pay attention to the installation
directions and conditions. (See page 11)
The inverter will be damaged if the power voltage is applied to its output terminal.
Applying power voltage to the output terminal U, V or W will damage the inverter.
Check carefully for fault wiring and operation procedure.
Never apply a power voltage that exceeds the tolerable voltage of the inverter.
Never touch the inside of the inverter during operation.
This is extremely dangerous the inverter contains high-voltage circuit. Be sure
to wait at least 5 minutes after the inverter power has been turned OFF, before
making an internal check.
Do not touch the heat sink fins or brake resistor during operation as these parts
will become hot during operation.
Radio interference
The main circuit of the inverter contains a higher harmonic component and may
interfere with communications equipment such as AM radios if these are used nearby.
The amount of radio interference depends on the field strength in the area where
the inverter is used. While it is difficult to completely eliminate radio interference,
it may be reduced by changing the angle of your radio antenna, using a noise
filter with the inverter, housing the inverter in a metallic shield box, or routing
inverter cables in metal conduit. ( Please inquire separately.)
Do not attempt insulation testing between the inverter cables.
To measure the insulation resistance of the power supply cables or the motor
cables, disconnect the inverter connecting wiries and test them with electric
connecting wires. Never conduct insulation testing on the control circuits by
megohm meter. However, insulation testing can be performed between the
charging unit and the ground.
If a magnetic contactor is connected to the power supply side or the load side
of the inverter, never use it to start or stop the motor (door controller).
Switching the inverter on the power supply side ON and OFF frequently by a magnetic
contactor, can cause the inverter to malfunction. Do not turn the inverter on the load
side ON and OFF during operation as this causes inverter fault trips. Start or stop
the motor only by means of inverter run signal.
Do not connect a power factor capacitor or suppressor to the output terminal
of the inverter.
Such devices can damage the inverter, its capacitors and other parts. Remove
the device if one is connected.
