9.3
Protective measures
Take the following protective measures into account.
9.3.1
Power grid supply in case of parallel connection
All drive controllers must be connected to the same supply grid.
ATTENTION!
Damage to device due to the emission of electromagnetic interference!
If the EMC threshold limits are exceeded during the operation of a DC link connection, devices in the immediate area can be
interrupted or damaged.
▪
Take suitable measures to comply with the electromagnetic compatibility.
▪
Always route the shortest possible connections for DC links. If they are longer than 30 cm, they must be shielded.
ATTENTION!
Damage to device in case of drive controller failure!
The failure of a drive controller in the DC link can result in damage to additional drive controllers.
▪
A failure must trigger the isolation of the entire DC link group from the grid.
Wiring example

link connection.
