IRMCS1071

ATTENTION: IRMCS1071 system contains ESD (Electrostatic Discharge) sensitive

parts and assemblies. Static control precautions are required when installing, testing,

servicing or repairing this assembly. Component damage may result if ESD control

procedures are not followed. If you are not familiar with static control procedures,

reference applicable ESD protection handbook and guideline.

ATTENTION: An incorrectly applied or installed drive can result in component

damage or reduction in product life. Wiring or application errors such as under sizing

the motor, supplying an incorrect or inadequate AC supply, or excessive ambient

temperatures may result in system malfunction.

!

ATTENTION: Remove and lock out power from the drive before you disconnect or

reconnect wires or perform service. Wait three minutes after removing power to

discharge the bus voltage. Do not attempt to service the drive until bus voltage has

discharged to zero. Failure to do so may result in bodily injury or death.

!

ATTENTION: Do not connect power factor correction capacitors to drive output

terminals U, V, and W. Doing so may result in equipment damage or bodily injury.

!

ATTENTION: IRMCS1071 system includes a field-weakening control function.

However, if a drive trip occurs in field-weakening operation, excessive DC bus over-

voltage will result. Users should take the necessary precautions to protect against DC

bus over-voltage. Failure to do so may result in equipment damage or bodily injury.
