Wiring instructions for shutter relays

Checking the installation instructions of the L5501RBCP, I saw in Figure 1 that the shutter relay distributes neutral on the shutter motor.

I was wondering if this is important for the correct function of the shutter relay. I mean if I wire neutral from the same neutral bar to both shutter relay and shutter motor isn't it the same?

 

The shutter relay unit breaks both the active and the neutral connection to the motor when the motor is stopped. This is a requirement in some markets where C-Bus products are sold. It also makes it fairly easy to wire the motor up, as you just run a single feed all the way back to the Shutter Relay unit, although this is a fairly minor point.

The neutral connections can be left un-connected as it is not a required connection for correct operation, provided you are meeting the wiring regulations in your country.
