4.1 System connection
Risk of electric shock and fire from a network with an impedance that is too low
Excessively high short-circuit currents can lead to the protective devices not being able to
interrupt these short-circuit currents and being destroyed, and so causing electric shock or
a fire.
• Ensure that the uninfluenced short-circuit current at the line terminal of the drive does
Death or severe personal injury from electrical shock
The earth leakage current for the drive can be greater than AC 3.5 mA, which may cause
death or severe personal injury due to electrical shock.
• A fixed earth connection is required to eliminate the dangerous leakage current. In
Electric shock due to touching PE connectors
When the equipment is working, hazardous touch current can be present at the PE
connectors; if touched, this can result in death or severe personal injury.
• Do not touch the PE connector during operation or within a certain period since power
Note
Interruptions of the internal protective bonding of the equipment caused by cable movement
The interruptions of the internal protective bonding of the equipment may be caused by cable
movement such as dragging cables.
• Do not drag cables when in operation.
• Make sure that you have performed appropriate protective measures for the protective
bonding when moving cables.
Note
