Safety instructions
3ADW000195R0501 DCS800 Service Manual e e
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 in-
tended 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.
