The minimum length of motor cables from the power unit to a common point of coupling is
10 m. When a du/dt filter is used, the cables can be less than 10 m long.
The optional external power connection block enables the connection of 3 motor cables to 1
terminal. It is also easier to connect large motor cables when you have this option.
The external power connection block is a loose option, install it near the IP00 drive module.
The cables between the motor cable terminals of the drive and the external power
connection block are not included in the delivery.
