Safety precautions

Page 12 / 52

CAUTION Check the following during and after the test run. Otherwise, there is a

danger of machine breakage:
Was the short cut bar between ter1 and + removed by mistake?
Was the running direction of the motor correct?
Was the inverter tripped during acceleration or deceleration?
Were the indications of the rpm and the frequency meter correct?
Were there any abnormal motor vibrations or noise?

Maintenance and inspection

WARNING Before carrying out maintenance and inspection wait for at least five minutes

after having turned off the input power supply. Otherwise, there is a danger of
electric shock.

WARNING When removing connectors (e.g. from fans and printed circuit boards) never

pull the attached wires. Otherwise, there is a danger of fire due to wire
breakage and/or injury.

Others

CAUTION

Withstand voltage tests and insulation resistance tests (megger tests) are
executed before the units are shipped, so that there is no need to conduct
these tests before operation.

CAUTION

Do not attach or remove wiring or connectors when power is applied. Also, do
not check signals (e.g. using a multimeter) during operation.

CAUTION

Never stop motor operation by switching off the electromagnetic contactors on
the primary or secondary side of the inverter.

When there has been an instantaneous power failure, and if an operation
instruction has been given, then the inverter may restart operation after the
power failure has ended. If there is a possibility that such an occurrence may
harm humans, then install an electromagnetic contactor on the primary (power
supply) side of the inverter, so that the circuit does not allow automatic
restarting after the power supply has recoverd. If the optional remote operator
is used and the retry function has been selected, this will also cause automatic
restarting when an operation instruction has been input, so please be careful.

CAUTION

Do not insert leading power factor capacitors or surge absorbers between the
output terminals of the inverter and the motor.
