DANGER
Electrical Shock Hazard
Do not change wiring, remove covers, connectors or options cards, or attempt to service the drive with power
applied to the drive.
Disconnect all power to the drive, and lock out the power source. After shutting off the power wait for at least the
amount of time specified on the drive front cover safety label. Measure the DC bus voltage for unsafe voltages to
confirm safe level before servicing to prevent electric shock. The internal capacitor remains charged even after the
power supply is turned off. Failure to comply will result in serious injury or death from electric shock.
W ARNING
Electrical Shock Hazard
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
The diagrams in this section may show drives without covers or safety shields to show details. Be sure to reinstall
covers or shields before operating the drives and run the drives according to the instructions described in this manual.
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing, and wear eye protection before beginning
work on the drive.
Fire Hazard
Drive Short-Circuit Current Rating
Install adequate branch circuit protection according to applicable local codes and this Installation Manual.
Failure to comply could result in fire and damage to the drive or injury to personnel.
The device is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 240
Vac maximum (200 V class) and 480 Vac maximum (400 V class) when protected by branch circuit protection devices
specified in this manual.
Do not use improper combustible materials in drive installation.
Failure to comply could result in death or serious injury by fire.
Attach the drive or braking resistors to metal or other noncombustible material.
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire. Verify that the rated voltage of the drive matches the
voltage of the incoming power supply before applying power.
The braking resistor connection terminals are B1 and B2. Do not connect a braking resistor directly to any
other terminals.
Improper wiring connections could result in death or serious injury by fire.
