YASKAWA iQpump1000 Installation & Start?Up Manual page 7

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 or megger 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.
Check for short circuits or ground faults on the secondary side of fuses and GFCIs and check the wiring and the selection of
peripheral devices. Remove the cause of the problem and then turn the power supply off and on again. If the cause cannot
be identified, do not turn on the power supply or attempt to operate the equipment.
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.
n General Application Precautions
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.
• when the power supply is above 600 kVA.
• when the drive is running from a power supply system with thyristor converters.
Note: A DC link choke is built in to drive models 2A0110 to 2A0415, 4A0058 to 4A1200, and 5A0041 to 5A0242.
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].
