Connect the Power Supply
Power is supplied to the Controller by a 12V DC power supply connected to the N+ and N- terminals. The
Controller does not contain internal regulation or isolation and we recommend using an ICT PRT-PSU-DIN for
this purpose, although any clean 12V DC supply is suitable.
Warning: Termination of wiring to the Controller while power is applied or the battery is connected
may cause serious damage to the unit and will VOID ALL WARRANTIES OR GUARANTEES. Power
the unit only after all wiring, configuration and jumper settings are completed.
If using a PRT-PSU-DIN module, a battery backup must be connected to the module network to provide a
monitored supply. The battery plays an important role in power conditioning and provides a continuous source
of power in the event of a power outage.
