• 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 sufficient 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 fieldbus). 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
configured 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, first press the LOC/REM key LOC
and then the stop key .
