Daikin ACS320 User Manual

• All ELV (extra low voltage) circuits connected to the drive
must be used within a zone of equipotential bonding,
ie within a zone where all simultaneously accessible
conductive parts are electrically connected to prevent
hazardous voltages appearing between them. This is
accomplished by a proper factory grounding.
NOTE: Even when the motor is stopped, dangerous voltage
is present at the power circuit terminals U1, V1, W1
and U2, V2, W2. For more technical information,
contact your local Daikin sales representative.
General Safety
DANGER
Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• Never attempt to repair a malfunctioning drive; contact
your local Daikin sales representative or authorized
Daikin Service for service support.
• Make sure that dust from drilling does not enter the drive
during the installation. Electrically conductive dust inside
the drive may cause damage or lead to malfunction.
• Ensure sufcient cooling.
Safe Start-Up and Operation
These warnings are intended for all who plan the operation,
start up or operate the drive.
General Safety
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 will reset the drive and resume operation after
a fault.
• Do not control the drive with an AC contactor or
disconnecting device (disconnecting means); use
the control panel start and stop keys and or external
commands (I/O or eldbus). The maximum allowed
number of charging cycles of the DC capacitors (ie
power-ups by applying power) is two per minute and the
maximum total number of chargings is 15,000.
NOTE: If an external source for start command is selected
and it is ON, the drive will start immediately after an
input voltage break or fault reset unless the drive is
congured for 3-wire (a pulse) start/stop.
When the control location is not set to local (LOC not
shown on the display), the stop key on the control
panel will not stop the drive. To stop the drive using
the control panel, rst press the LOC/REM key LOC
and then the stop key.
