Yaskawa Z1000 AC Drive HVAC - Manual (Page 15)

WARNING
Install adequate branch circuit protection according to applicable local codes and this Installation Manual. Failure
to comply could result in fire and damage to the drive or injury to personnel.
The device is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 600 Vac
maximum (600 V class) when protected by branch circuit protection devices specified in this document.
Branch circuit protection shall be provided by any of the following: Non-time delay Class J, T, or CC fuses sized at 300%
of the drive input rating, or Time delay Class J, T, or CC fuses sized at 175% of the drive input rating, or MCCB sized at
200% maximum of the drive input rating.
Crush Hazard
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.
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.
If a fuse is blown or a Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of the
peripheral devices.
Contact your supplier if the cause cannot be identified after checking the above.
Do not restart the drive immediately operate the peripheral devices if a fuse is blown or a GFCI is tripped.
Check the wiring and the selection of peripheral devices to identify the cause. Contact your supplier before restarting the
drive or the peripheral devices if the cause cannot be identified.
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.
u General Application Precautions
n Selection
Installing a Reactor
Use an AC reactor or DC link choke in the following situations:
• to suppress harmonic current.
• to smooth peak current that results from capacitor switching.
