3.1 Section Safety
Do not use improper combustible materials in drive installation.
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 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.
The braking resistor connection terminals are B1 and B2. Do not connect a braking resistor directly to any other
terminals.
Improper wiring connections could result in death or serious injury by fire.
Carrying the drive by the front cover may cause the main body of the drive to fall, resulting in minor or
moderate injury.
Always hold the case when carrying the drive.
Do not carelessly connect parts or devices to the drives braking transistor terminals.
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 share the ground wire with other devices such as welding machines or large-current electrical
equipment.
Improper equipment grounding could result in drive or equipment malfunction due to electrical interference.
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.
Use care when connecting parts or devices to the drives braking transistor terminals.
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 any modification of the product made by the user. This product must not be modified.
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.
