YASKAWA L1000V Technical Manual page 192

7.1 Section Safety
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other
devices.
Failure to comply could result in damage to the drive.
Make sure wiring to motor terminals U, V, and W connect the corresponding U/T1, V/T2, and W/T3 output
terminals on the drive.
Wiring to the wrong terminals will reverse the phase order, causing the motor to operate in reverse. This could cause
the elevator car to fall when attempting to go up.
Never use a magnet contactor on the input side of the drive.
Refrain from switching an input contactor more often than once every 30 minutes. Normally the drive I/O should be
used to stop and start the motor.
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.
