Connection examples for motor starters
The installation guidelines for AS-Interface must always be observed:
● The maximum permissible current for all M12 connection cables is restricted to 4 A.
● The maximum permissible current for all M12 connection cables is restricted to 4 A.
The cross-section of these cables is just 0.34 mm². To connect the motor starter, you can
use the M12 connection cables mentioned above as spur lines.
● The voltage drop induced by the ohmic resistance (approx. 0.11 Ω/m) must be taken into
account.
● The following maximum lengths apply to round cable connections in which AS-i and U
AUX
are routed in the same cable:
– For each spur line from the branch to the module: max. 5 m
– Total of round cable components in one AS-Interface network: max. 20 m
– For each spur line from the branch to the module: max. 5 m
– Total of round cable components in one AS-Interface network: max. 20 m
