WARNING
Fire Hazard. Tighten screws at an angle in the specified range shown in this manual. If
you tighten the screws at an angle not in the specified range, you can have loose connections that can cause
damage to the terminal block or start a fire and cause serious injury or death.
WARNING
Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. A short
circuit on the output can cause serious injury or death.
WARNING
Electrical Shock Hazard. When there is a DC component in the protective earthing
conductor, the drive can cause a residual current. When a residual current operated protective or monitoring
device prevents direct or indirect contact, always use a type B Residual Current Monitor/Residual Current Device
(RCM/RCD) as specified by IEC/EN 60755. If you do not use the correct RCM/RCD, it can cause serious injury or
death.
WARNING
Electrical Shock Hazard. Ground the neutral point on the power supply of drive models
2xxxE, BxxxE, and 4xxxE to comply with the EMC Directive before you turn on the EMC filter or if there is high
resistance grounding. If the EMC filter is switched ON without the neutral point being grounded or if there is high
resistance grounding, it can cause death or serious injury.
WARNING
Crush Hazard. Test the system to make sure that the drive operates safely after you wire
the drive and set parameters. If you do not test the system, it can cause damage to equipment or serious injury or
death.
WARNING
Electrical Shock Hazard. After the drive blows a fuse or trips an RCM/RCD, do not
immediately energize the drive or operate peripheral devices. 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. If you do not know the cause of the problem, contact Yaskawa before you energize the
drive or peripheral devices. If you do not fix the problem before you operate the drive or peripheral devices, it can
cause serious injury or death.
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 31,000 RMS
symmetrical amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class). Incorrect branch
circuit short circuit protection can cause serious injury or death.
CAUTION
Crush Hazard. Tighten terminal cover screws and hold the case safely when you move the
drive. If the drive or covers fall, it can cause moderate injury.
CAUTION
Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum
of 15 minutes, then make sure that the heatsink is cool before you replace the cooling fans. If you touch a hot
drive heatsink, it can burn you.
NOTICE
When you touch the drive and circuit boards, make sure that you observe correct
electrostatic discharge (ESD) procedures. If you do not follow procedures, it can cause ESD damage to the drive
circuitry.
NOTICE
Do not break the electrical connection between the drive and the motor when the drive is
outputting voltage. Incorrect equipment sequencing can cause damage to the drive.
NOTICE
Do not do a withstand voltage test or use a Megger insulation tester on the drive. These
tests can cause damage to the drive.
NOTICE
Do not operate a drive or connected equipment that has damaged or missing parts. You
can cause damage to the drive and connected equipment.
NOTICE
Install a fuse and equipment for residual current monitoring/detection (RCM/RCD). If you
do not install these components, it can cause damage to the drive and connected equipment.
NOTICE
Before you connect a dynamic braking option to the drive, make sure that qualified
personnel read and obey the Braking Unit and Braking Resistor Unit Installation Manual (TOBPC72060001). If
you do not read and obey the manual or if personnel are not qualified it can cause damage to the drive and
braking circuit.
NOTICE
Make sure that all connections are correct after you install the drive and connect
peripheral devices. Incorrect connections can cause damage to the drive.
NOTICE
Do not connect phase-advancing capacitors, LC/RC noise filters, or leakage breakers
(RCM/RCD) to the motor circuit. If you connect these devices to the output circuits, it can cause damage to the
drive and connected equipment.
