General Application Precautions - YASKAWA A1000 Technical Manual

Do not use this drive in lifting applications without installing external safety circuitry to prevent accidental dropping
of the load.
The drive does not possess built-in load drop protection for lifting applications.
Failure to comply could result in death or serious injury from falling loads.
Install electrical and/or mechanical safety circuit mechanisms independent of drive circuitry.
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.
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 use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 240 Vac
maximum (200 V Class), 480 Vac maximum (400 V Class), and 600 Vac maximum (600 V Class) when protected by
Bussmann Type FWH or FWP fuses as specified in
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.

General Application Precautions

n Selection
Installing a Reactor
Use an AC or DC reactor in the following situations:
• to suppress harmonic current.
• to smooth peak current that results from capacitor switching.
• when the power supply is above 600 kVA.
• when the drive is running from a power supply system with thyristor converters.
Note: A DC reactor is built in to drive models CIMR-Ao2A110 to 2A0415 and 4A0058 to 4A1200.
