Yaskawa J1000 Compact V/f Control Drive - Manual (Page 39)

3.2 Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 3. . 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 69 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 31,000 RMS symmetrical amperes, 240 Vac maximum (200 V Class) and 480 Vac
maximum (400 V Class).
NOTICE: When 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: Correctly set Sink/Source jumper S3 for internal power supply. Failure to comply may result in
damage to the drive. Refer to I/O Connections on page 59 for details.
NOTICE: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause
control circuit malfunction.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible
interference related issues. Failure to comply may result in abnormal operation of drive and nearby equipment.
NOTICE: The minimum load for the multi-function relay output MA-MB-MC is 10 mA.
