Extending power wires to implement safety features

In your manual you show both a fuse and an emergency disconnect switch between the batteries and the motor controller. My team would like to implement these safety features but we have also read in the manual that the power wires should not be extended. We have an inline fuse which would add about 6 inches in length to the cables as well as a disconnect switch and we were wondering if it is ok to add this to the end of the two positive battery wires or if we should shorten the battery wires to account for the extra length.

Adding the kind of wire length you indicate is OK and will not affect functionality.
