<2> The MC on the input side of the main circuit should open when the thermal relay is
triggered.
<3> Self-cooled motors do not require separate cooling fan motor wiring.
<4> Connected using sequence input signal (S1 to S7) from NPN transistor; Default: sink
mode (0 V com).
<5> Use only a +24 V internal power supply in sinking mode; the source mode requires
an external power supply.
<6> Monitor outputs work with devices such as analog frequency meters, ammeters,
voltmeters and wattmeters; they are not intended for use as a feedback-type of signal.
<7> Disconnect the wire jumper between HC and H1 when utilizing the safety input.
to Wiring Procedure on page 71
for the Safe Disable input should not exceed 30 m.
<8> Note that if the drive is set to trigger a fault output whenever the fault restart function
is activated (L5-02 = 1), then a sequence to interrupt power when a fault occurs will
result in shutting off the power to the drive as the drive attempts to restart itself. The
default setting for L5-02 is 0 (fault output active during restart attempt).
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction
input terminal parameter is properly set (S5 for 3-Wire; H1-05 = "0"). Improper sequencing of run/stop circuitry
could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the
correct state before energizing the drive. Failure to comply could result in death or serious injury from moving
equipment. When programmed for 3-Wire control, a momentary closure on terminal S1 may cause the drive
to start.
WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control
terminals and ensure parameter b1-17 is set to 0 (drive does not accept a run command at power up (default).
If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence (default) and if parameter b1-17 is
set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction at power up of
the drive and may cause injury.
WARNING! When the application preset function is executed (or A1-06 is set to any value other than 0) the
drive I/O terminal functions change. This may cause unexpected operation and potential damage to
equipment or injury.
