WARNING! Fire Hazard. Do not put flammable or combustible materials on top of the drive and do not install the drive near
flammable or combustible materials. Attach the drive to metal or other noncombustible material. Flammable and combustible
materials can start a fire and cause serious injury or death.
WARNING! Fire Hazard. Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too tight can
cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious injury from fire.
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! Crush Hazard. Use a crane or hoist to move large drives when necessary. If you try to move a large drive without a
crane or hoist, it can 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 Ground Fault Circuit Interrupter (GFCI) as specified by IEC/EN 60755. If you do not use the correct GFCI, it can cause
serious injury or death.
WARNING! Electrical Shock Hazard. Ground the neutral point on the power supply of drive models 2xxxB/C and 4xxxB/C to comply
with the EMC Directive before you turn on the EMC filter. If you turn ON the EMC filter, but you do not ground the neutral point, it can
cause serious injury or death.
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 a GFCI, 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! Crush Hazard. Only approved personnel can operate a crane or hoist to move the drive. If unapproved personnel
operate a crane or hoist, it can cause serious injury or death from falling equipment.
WARNING! Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this manual.
The drive is suitable for circuits that supply not more than 100,000 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: Damage to Equipment. 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: Damage to Equipment. Do not do a withstand voltage test or use a megohmmeter or 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 branch circuit protection, for example fuses or ground fault circuit interrupters (GFCIs) as specified in the drive
instructions. If you do not install these components, it can cause damage to the drive and connected equipment.
NOTICE: Damage to Equipment. 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 (GFCI) to the motor circuit. If you
connect these devices to the output circuits, it can cause damage to the drive and connected equipment.
NOTICE: Use an inverter-duty motor or vector-duty motor with reinforced insulation and windings applicable for use with an AC
drive. If the motor does not have the correct insulation, it can cause a short circuit or ground fault from insulation deterioration.
Note:
Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive.
Unshielded wire can cause electrical interference and unsatisfactory system performance.
