In a small installation this same power supply can be used to supply the module network as well, so long as the
maximum load of the power supply is not exceeded. In larger installations, the power supply may need to be
split to allow for load sharing between several supplies.

Example Multiple PSU Connection
Warning: When using multiple power supplies it is important to ensure that all ground connections (V-)
are connected between all power supplies and that no power connections (V+) are connected
between any power supplies.
The auxiliary outputs (V- V+) of the PRT-CTRL-DIN can be used to supply other equipment. Note that there is
no onboard regulation or isolation for these outputs and they are a fused feed-through from the N+ N- input
terminals. When using these outputs to supply other devices, you need to ensure you do not exceed the rating
of the internal fuses as described in the Technical Specifications (see page 7).
