Connection of the 24 V busbars
The 24 V busbars of the components are connected using the 24 V connectors. The 24 V
connectors are provided in the accessories pack.
• Plug a 24 V connector onto each of the 24 V busbars between the Line Module, Motor Module
and DC link component.
• All of the 24 V connectors must be inserted before commissioning.
WARNING
Fire hazard for 24 V connectors and unconnected DC link busbars
For drive lineups in series, whose DC link busbars are not connected with one another, it is not
permissible to insert 24 V connectors between these drive lineups. Otherwise the 24 V
connectors can burn and cause severe injury or death as result of fire or smoke.
• If the DC link busbars of the components are not connected with one another, then you
must use a 24 V terminal adapter for each component to establish the 24 V supply.
NOTICE
Damage to the 24 V connector as a result of incorrect insertion/withdrawal
Incorrect insertion/withdrawal of a 24 V connector can damage it.
• It is only permissible to withdraw or insert 24 V connectors a maximum of 5 times.
