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.
