1 Safety Instructions and General Warnings
EN 6 YASKAWA Europe TOEP C710616 92D AC Drive L1000H Quick Start Guide
System may start unexpectedly upon application of power, resulting in death or serious injury.
Clear all personnel from the drive, motor, and machine area before applying power. Secure covers, couplings, shaft
keys, and machine loads before applying power to the drive.
Fire Hazard
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.
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.
Do not use improper combustible materials in drive installation, repair or maintenance.
Failure to comply could result in death or serious injury by fire. Attach the drive or braking resistors to metal or other
noncombustible material.
Do not connect the AC power line to the output motor terminals of the drive.
Failure to comply could result in death or serious injury by fire as a result of drive damage from line voltage
application to output terminals.
• Do not connect AC line power to output terminals U, V, and W.
• Make sure that the power supply lines are connected to main circuit input terminals R/L1, S/L2, T/L3 (or R/L1 and S/
L2 for single-phase power).
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
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.
Burn Hazard
Do not touch the heatsink or braking resistor hardware until a powered-down cooling period has elapsed.
Equipment Hazard
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.
Never connect or disconnect the motor from the drive while the drive is outputting voltage.
Improper equipment sequencing could result in damage to the drive.
Do not perform a withstand voltage test on any part of the unit.
Failure to comply could result in damage to the sensitive devices within the drive. Use power off resistance checks to
determine shortcircuits.
