This chapter provides engineering information for a common DC bus for several drives.

Incorrect use of the DC bus may permanently damage the drives either immediately or over time.

WARNING

DESTRUCTION OF SYSTEM COMPONENTS AND LOSS OF CONTROL

Verify that all requirements for using the DC bus are met.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

DESTRUCTION OF SYSTEM COMPONENTS

•Connect only drives with identical nominal voltages.

•Connect single-phase drives only to single-phase drives. Connect single-phase drives to the same phase.

•Connect three-phase drives only to three-phase drives.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

LXM32: See the Engineering chapter in the LXM32 product manual for vital engineering information concerning the LXM32 drive.
