♦
♦♦
♦Use your inverter only within tolerable ambient temperature range.
(–10°C to 50°C)
Because the life of the inverter is greatly affected by ambient temperature, do
not use it outside the specifications. Also, pay attention to the installation
direction's and conditions. (See page 12.)
♦
♦♦
♦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 for miswiring and operation sequence (commercial
changeover circuit, etc.). Never apply a 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 them from the inverter. Never conduct insulation testing
on the control circuits. However, insulation testing can be performed between
the charging unit and the ground.
♦
♦♦
♦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.
Special Precautions

11
♦
♦♦
♦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 (inverter).
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 start input signals.
♦
♦♦
♦Do not use this inverter for loads other than a motor or for single-phase
motors.
♦
♦♦
♦Precautions regarding inverter's protection function
Various protection functions, such as stall prevention, current limiting and
overcurrent protection, are incorporated in the inverter.
These protection functions are used to protect the inverter from unexpected
faults that could occur during use of the inverter, and are not the control
functions normally used.
Thus, during normal usage, avoid applications that activate these protection
functions.
Depending on the state, the inverter life could drop, or damage could occur.
Before using the inverter, measure the output current, etc., with a measuring
instrument, and check the details of the fault trip memory. Make sure that
there are no problems in respect to the all precautions listed in this instruction
manual, including those above, and in respect to the product specifications.
♦
♦♦
♦The CE Mark attached to the inverter complies with the Low Voltage
Directive.
♦
♦♦
♦Measure the electromagnetic compatibility (EMC) in the state assembled
in the machine.
♦
♦♦
♦Only basic insulation (Protection against Electric Shock Class I
II
I,
Overvoltage category II
IIII
II, Pollution degree 2) is provided on the control
circuit terminals.
The supplementary insulation must be provided on the final product to
comply with CE Marking requirements.
♦
♦♦
♦Make sure to ground the supply neutral.
♦
♦♦
♦Always connect protective devices such as fuses for overcurrent, short
circuits and leakage protection to the power supply input.
♦
♦♦
♦Always use a ring crimp terminal for the main circuit wiring (R/L1, S/L2,
T/L3, U, V, W).
♦
♦♦
♦Only for machinery with fixed connection.
