Safety Information
General
DANGER
To Prevent Electric Shock
ƕ Never wire the AC drive while the power is on. Cut off all power supplies and wait for at least ten minutes
before any checking work so that the residual voltage on capacitors can discharge safely.
ƕ Always ensure that the AC drive is tied to ground well because the contact current of the drive is larger than 3.5 mA.

ƕ Always handle the drive with care.
ƕ Do not use the drive if there are damaged or missing parts.
To Prevent Damage to the Equipment
ƕ Follow the proper electrostatic discharge (ESD) procedures when operating the AC
drive. Failure to comply will damage the interna circuit of the drive.
ƕ Do not perform a voltage resistance test on any part of the AC drive. The factory performs tests
of this type during manufacture and damage might occur if you repeat these tests.
ƕ Do not power on or operate the drive that has been damaged or has any missing part. Failure to comply may cause further damage.
ƕ Perform branch circuit and short circuit protection according to local code. Failure to comply may damage the drive. The drive
is applicable to the circuit capable of 100 kA below short-circuit current and and 480 VAC maximum voltage (400 V class).
To Reduce Interference
ƕ Never install equipments such as transformer that generate electromagnetic wave or interference
surrounding the drive. Failure to comply may result in unexpected action of the drive. If it is
necessay to install such equipment, install a shield plate between it and the drive.
To Prevent Malfunction
ƕ Never share grounding cable with welding machines or electrical equipments that require large
current. Failure to comply may result in the drive or equipment malfunction.
ƕ When using multiple drives, ground them properly according to the instructions in this
manual. Improper grounding may result in the drive or equipment malfunction.
