CAUTION
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Do not perform a withstand voltage test on any part of the drive.
Failure to comply could result in damage to the sensitive devices within the drive.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
Install adequate branch circuit short circuit protection per applicable codes.
Failure to comply could result in damage to the drive.
The drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 600 Vac maximum
(600 V Class).
Do not expose the drive to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the drive.
Do not pack the drive in wooden materials that have been fumigated or sterilized.
Do not sterilize the entire package after the product is packed.

Selection
Installing a Reactor
Use an AC or DC reactor in the following situations:
• to suppress harmonic current.
• to smooth peak current resulting from capacitor switching.
• when the power supply is above 600 kVA.
• when the drive is running from a power supply system with thyristor converters.

Drive Capacity
For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.
When running more than one motor in parallel from a single drive, the capacity of the drive should be larger than [total motor
rated current × 1.1].
