3ADW000488R0101 DCS880 Service manual e a
Operation
These warnings are intended for all who plan the operation of the drive or operate the drive. Ignoring the
instructions can cause physical injury or death and/or damage to the equipment.
WARNING
−
Before adjusting the drive and putting it into service, make sure that the motor and all
driven equipment are suitable for operation throughout the speed range provided by the
drive. The drive can be adjusted to operate the motor at speeds above and below the base
speed.
−
Do not control the motor with the disconnecting device (disconnecting mains); instead, use
the control panel keys
and
, or commands via the I/O board of the drive.
−
Mains connection:
You can use a disconnect switch (with fuses) to disconnect the electrical components of
the drive from the mains for installation and maintenance work. The type of disconnect
switch used must be as per EN 60947-3, Class B, so as to comply with EU regulations, or a
circuit-breaker type which switches off the load circuit by means of an auxiliary contact
causing the breaker's main contacts to open. The mains disconnect must be locked in its
"OPEN" position during any installation and maintenance work.
−
EMERGENCY STOP buttons must be installed at each control desk and at all other control
panels requiring an emergency stop function. Pressing the STOP button on the control
panel of the drive will neither cause an emergency stop of the motor, nor will the drive be
disconnected from any dangerous potential.
−
To avoid unintentional operating states, or to shut the unit down in case of any imminent
danger according to the standards in the safety instructions it is not sufficient to merely shut
down the drive via signals "RUN", "drive OFF" or "Emergency Stop" respectively "control
panel" or "PC tool".
−
Intended use:
−
The operating instructions cannot take into consideration every possible case of
configuration, operation or maintenance. Thus, they mainly give such advice only, which is
required by qualified personnel for normal operation of the machines and devices in
industrial installations.
−
If in special cases the electrical machines and devices are intended for use in non-
industrial installations - which may require stricter safety regulations (e.g. protection against
contact by children or similar) - these additional safety measures for the installation must
be provided by the customer during assembly.
Note:
−
When the control location is not set to Local (Local not shown in the status row of the
display), the stop key on the control panel will not stop the drive. To stop the drive using the
control panel, press the Loc/Rem key and then the stop key
.
