WARNING
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 Yaskawa before energizing the drive or peripheral devices if the cause is not
known. Failure to obey can cause death or serious injury and damage to the drive.
WARNING
Fire Hazard. Install sufficient branch circuit short circuit protection as specified by
applicable codes and this manual. The drive is suited for circuits that supply not more than 100,000 RMS
symmetrical amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class). Failure to obey can
cause death or serious injury.
CAUTION
Crush Hazard. Do not hold the drive by the front cover or terminal cover. Tighten the
screws correctly before moving the drive. Failure to obey can cause minor to moderate injury.
CAUTION
Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait 15 minutes
minimum, and make sure that the heatsink is cool to replace the cooling fans. Failure to obey can cause minor to
moderate injury.
NOTICE
Observe correct electrostatic discharge (ESD) procedures when touching the drive and
circuit boards. Failure to obey can cause ESD damage to the drive circuitry.
NOTICE
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.
NOTICE
Do not do a withstand voltage test or Megger test on the drive. Failure to obey can cause
damage to the drive.
NOTICE
Do not connect or operate damaged equipment or equipment with missing parts. Failure to
obey can cause damage to the drive and connected equipment.
NOTICE
Install fuses and an RCM/RCD. Failure to obey can cause damage to the drive.
NOTICE
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 obey can cause electrical interference and unsatisfactory
system performance.
NOTICE
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.
NOTICE
Make sure that all connections are correct after you install the drive and connecting
peripheral devices. Failure to obey can cause damage to the drive.
NOTICE
Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.
Failure to obey can cause damage to the drive, phase-advancing capacitors, LC/RC noise filters, and leakage
breakers (ELCB, GFCI, or RCM/RCD).

Intended Use
This communication option card is electrical equipment intended to enable Yaskawa drives to
communicate with an additional fieldbus system for commercial use. Do not use this product for
any other purpose.
1.
Read and understand all safety precautions.
2.
Wire and ground the drive and communication option card in accordance with all
applicable standards and safety precautions.
3.
Firmly attach all parts and protective covers.
4.
Always use the product in the proper environmental conditions as specified in this manual.
DANGER
Electrical Shock Hazard. Make sure that all electrical connections are correct and install all
drive covers before energizing the drive. Use terminals for their intended function only. Incorrect wiring or ground
connections, and incorrect repair of protective covers can cause death or serious injury.
