Operational warnings
Warning!
If the supply voltage recovers after an intermittent
failure, the motor may restart automatically if a start
signal is still present. If personnel is endangered as a
result, an external circuit must be provided which
prevents a restart after voltage recovery.
Warning!
If the frequency inverter has been configured so that the
stop signal is not issued through the OFF key on the LCD
keypad, pressing the OFF key will not switch off the
motor.
Warning!
Before carrying out maintenance and inspection work on
the frequency inverter, wait at least five minutes after
the supply voltage has been switched off. Failure to
observe this point can result in electric shock due to high
equipment voltages.
Warning!
Never pull on the cable to unplug connectors (e.g. for
fan or circuit boards).
Warning!
If a reset is issued after a malfunction, the motor will
start automatically if a start signal is also present. To
avoid the risk of serious or fatal injury to personnel, you
must ensure that the start signal is not present before
acknowledging a fault message with a reset.
Warning!
When the supply voltage for the frequency inverter is
applied while the start signal is active, the motor will
start immediately. Make sure that the start signal is not
active before the supply voltage is switched on.
Warning!
Do not connect cables or connectors during operation
when the supply voltage is switched on.
Caution!
To prevent a risk of serious or fatal injury to personnel,
never interrupt the operation of the motor by opening the
contactors installed on the primary or secondary side.
h
The ON key is functional only if the corresponding para-
meters of the frequency inverter have been configured
accordingly (a Section Setting the frequency and start
signal parameters, Page 123).
h
Before operating motors at frequencies above the stan-
dard 50 or 60 Hz, contact their manufacturers to verify
that the motors are suitable for operation at higher
frequencies. The motors could otherwise incur damage.
