Multi-drive Protection
Use a separate line reactor for each drive that shares a common power line.
Individual line reactors provide filtering between each drive to provide optimum
surge protection for each drive. However, if it is necessary to group more than one
drive on a single AC line reactor, use this process to verify that the AC line
reactor provides a minimum amount of impedance:
• In general, up to five drives can be grouped on one reactor.
• Add the input currents of the drives in the group.
• Multiply that sum by 125%.
• Refer to 1321 Power Conditioning Products Technical Data, publication
1321-TD001
, to select a reactor with a maximum continuous current
rating greater than the multiplied current.
