YASKAWA L1000A Quick Start Manual page 12

i Preface & General Safety
Do not change wiring, remove covers, connectors or options cards, or attempt to service the drive with power
applied to the drive.
Failure to comply could result in death or serious injury. Disconnect all power to the drive and check for unsafe
voltages before servicing.
Do not allow unqualified personnel to use the equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection, and replacement of parts must be performed only by authorized personnel familiar with
installation, adjustment and maintenance of AC drives.
Drive Short-Circuit Current Rating
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, 240
Vac maximum (200 V class) and 480 Vac maximum (400 V class), and 600 Vac maximum (600 V class) when
protected by branch circuit protection devices specified in this manual.
Applications using a braking option should wire a thermal relay so that the output contactor opens when the
thermal relay trips.
Inadequate braking circuit protection could result in death or serious injury by fire from overheating resistors.
Do not use improper combustible materials.
Failure to comply could result in death or serious injury by fire.
Attach the drive to metal or other noncombustible material.
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Failure to comply could result in damage to the drive or braking circuit.
Observe proper electrostatic discharge procedures (ESD) when handling the drive, circuit boards, and option
cards.
Failure to comply may result in ESD damage to the drive circuitry.
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 Ground Fault Circuit Interrupters (GFCI),
and check the wiring and the selection of peripheral devices. Remove the cause of the problem and then turn the power
supply 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.
