8.1 Section Safety
W ARNING
Sudden Movement Hazard
Install a properly controlled contactor on the input-side of the drive for applications where power should be
removed from the drive durnig a fault condition.
Improper equipment sequencing could result in death or serious injury.
NOTICE
Equipment Hazard
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.
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.
Insulate shields with heat shrink tubing or tape to prevent contact with other signal lines and equipment.
Improper wiring practices could result in drive or equipment malfunction due to short circuit.
Use a class 2 power supply (UL standard) when connecting to the control terminals.
Improper application of peripheral devices could result in drive performance degradation due to improper power
supply.
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.
Never use a magnet contactor on the input side of the drive frequently to start and stop the motor.
Failure to comply could result in damage to the drive.
Properly integrate auxiliary contacts into the control logic circuit to avoid unnecessary fault displays caused by
contactors or output switches placed between drive and motor.
Improper installation of input and output contactors could result in damage to the drive.
Improper application of devices on drive output circuits can damage the drive
Do not connect unapproved LC or RC interference suppression filters, capacitors, ground fault circuits, or overvoltage
protection devices to the drive.
Improper application of peripheral devices could result in malfunction of drive due to electrical interference.
Follow manufacturer recommendations when installing electrical devices near the drive and take precautions to shield
the drive from electrical interference.
Properly integrate auxiliary contacts into the control logic circuit to avoid unnecessary fault displays caused by
contactors or output switches placed between drive and motor.
