3.2 Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 3.1 . It is possible to run the drive via the digital operator
without connecting digital I/O wiring. This section does not discuss drive operation; Refer to Start-Up Programming &
Operation on page 51 for instructions on operating the drive.
NOTICE: Inadequate branch short circuit protection could result in damage to the drive. Install adequate branch circuit short circuit
protection per applicable codes. The drive is suitable for circuits capable of delivering not more than 30,000 RMS symmetrical amperes,
240 Vac maximum (200 V Class) and 480 Vac maximum (400 V Class).
NOTICE: When the input voltage is 440 V or higher or the wiring distance is greater than 100 meters, pay special attention to the motor
insulation voltage or use a drive duty motor. Failure to comply could lead to motor insulation breakdown.
NOTICE: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
NOTICE: The minimum load for the multi-function relay output MA-MB-MC is 10 mA.

<1> Remove the jumper when installing an optional DC reactor.
<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 S5) 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 Refer
to I/O Connections on page 44 .
<6> Minimum load: 5 Vdc, 10 mA (reference value).
