Connect the drive and peripheral devices as shown in Figure 3.1 . It is possible to set and run the drive via the digital
operator without connecting digital I/O wiring. This section does not discuss drive operation; Refer to Start-Up

WARNING! Sudden Movement Hazard. If holding brake circuits are not configured properly, load equipment may fall or drop during
power loss or drive fault, which could result in death or serious injury.
・
Provide a separate holding brake if necessary.
・
Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power failure,
or an abnormality in the drive.
・
When using the drive with an elevator, provide external safety measures to prevent the elevator from dropping.
NOTICE: Inadequate wiring 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 100,000 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 (328 ft.), pay special attention to
the motor insulation voltage or use a drive rated motor. Failure to comply could lead to motor insulation breakdown.
NOTICE: Do not connect control circuit ground (AC) to drive enclosure. Improper drive grounding can cause control circuit
malfunction.
NOTICE: The minimum load for the relay outputs MA-MB-MC and MD-ME-MF is 10 mA.
