Panasonic VF0 Series Instruction Manual page 12

♦ ♦ ♦ ♦ 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 I I I ,
Overvoltage category II II II 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.
