Safety Precautions

Before start-up, note the following directions and warnings:

WARNING

1Internal components and circuit boards of the drive are live when the drive is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.

2The motor terminals U, V, W and the DC-link/brake resistor terminals B+/R+, R- are live when the drive is connected to mains, even if the motor is not running.

3The control I/O-terminals are isolated from the mains potential. However, the relay outputs and other I/O- terminals may have a dangerous control voltage present even when the drive is disconnected from mains.

Do not make any connections when the drive is connected to the mains.

After having disconnected the drive, wait until the indicators on the keypad go out (if no keypad is attached see the indicator through the keypad base). Wait 5 more minutes before doing any work on drive connections. Do not even open the cover before this time has expired.
