3.1 Section Safety
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.
Connect braking circuits to the drive as shown in the I/O wiring examples.
Improperly wiring braking circuits could result in damage to the drive or equipment.
Install adequate branch circuit short circuit protection per applicable codes.
The drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac
maximum (200 V Class) and 480 Vac maximum (400 V Class). Inadequate branch short circuit protection damage or
serious injury by fire.
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.
