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 63
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 480 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. If a circuit requires less than 10 mA (reference
value), connect it to a photocoupler output (P1, P2, PC). Improper application of peripheral devices could result in damage to the
photocoupler output of the drive.
