Safety 11
Safety in start-up and operation
These warnings are intended for all who plan the operation, start up or operate the
drive.
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• 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 speed provided by connecting the motor directly
to the power line.
• Do not activate automatic fault reset functions if dangerous situations can
occur. When activated, these functions reset the drive and resume operation
after a fault.
• Do not control the motor with an AC contactor or disconnecting device
(disconnecting means); use instead the control panel start and stop keys and
or external commands (I/O). The maximum allowed number of charging
cycles of the DC capacitors (that is, power-ups by applying power) is two per
minute.
Note:
When parameter 1103 PRIMARY COMMAND SOURCE MODE is not set to 1 or 2,
the stop key on the control panel will not stop the drive. To stop the drive open
terminal 2 of the drive control terminals.
Danger: Indicates a risk of electric
shock, which, if not avoided, could
result in damage to the equipment
and possible injury or death. Danger: Indicates a potentially
hazardous situation other than
electrical, which if not avoided,
could result in damage to
property.
The ACS260 variable speed drive is intended for professional installation and
commissioning into complete equipment or systems as part of a fixed installation.
If installed incorrectly it may present a safety hazard. The
ACS260 uses high
voltages and currents, carries a high level of stored electrical energy, and is used
to control mechanical plant that may cause injury. Close attention is required to
system design and electrical installation to avoid hazards in either normal
operation or in the event of equipment malfunction. Only qualified electricians are
allowed to install and maintain this product.
System design, installation, commissioning and maintenance must be carried out
only by personnel who have the necessary training and experience. They must
carefully read this safety information and the instructions in this Guide and follow
all information regarding transport, storage, installation and use of the
ACS260 ,
including the specified environmental limitations.
