Power Requirements
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 any clean 12V DC supply is suitable for this purpose.
Termination of wiring to the module 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.
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.
For UL applications, must be powered by a UL Listed (UL 603 or UL 294) power limited power
supply capable of supplying at least 4 hours of standby power.
For ULC applications, must be powered by a ULC Listed (CAN/ULC S318 or CAN/ULC S319) power
limited power supply capable of supplying at least 24 hours of standby power.
