YASKAWA L1000A Technical Manual page 251

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.
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).
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 use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance. Use shielded twisted-pair
wires and ground the shield to the ground terminal of the drive.
Do not allow unqualified personnel to use the product.
Failure to comply could result in damage to the drive or braking circuit.
Carefully review instruction manual TOBPC72060000 when connecting a braking option to the drive.
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 modification of the product made by the user.
Check all the wiring after installing the drive and connecting other devices to ensure that all connections are
correct.
Failure to comply could result in damage to the drive.
Do not check or test control circuit signals while the drive is running.
Improper use of test equipment could result in damage to the drive circuitry by short circuit.
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.
