Electrical Shock Hazard
Do not immediately energize the drive or operate peripheral devices after the drive blows a fuse
or trips an RCM/RCD. Wait for the time specified on the warning label at a minimum and make
sure that all indicators are OFF. Then check the wiring and peripheral device ratings to find the
cause of the problem. Contact the manufacturer before energizing the drive or peripheral
devices if the cause is not known.

boards.
Failure to obey can cause ESD damage to the drive circuitry.
Do not connect or disconnect the motor from the drive while the drive is supplying voltage.
Incorrect equipment sequencing can cause damage to the drive.
Do not use unshielded wire for control wiring. Use shielded twisted-pair wires and ground the
shield to the ground terminal of the drive.
Failure to comply may cause electrical interference resulting in poor system performance.
Do not allow unqualified personnel to use the product. Before you connect a dynamic braking
option to the drive, make sure that you review Braking Unit and Braking Resistor Unit
Installation Manual TOBPC72060001.
Failure to obey can cause damage to the drive and braking circuit.
Do not change the drive circuitry.
Failure to obey can cause damage to the drive and will void warranty. The manufacturer is not responsible for
