Optional backup power supply
The PowerRouter provides users with a self-use system with backup power supply which intervenes in the
event of a power outage. The PowerRouter has two AC connections: an AC GRID and an active AC LOCAL
OUT. In the event of a grid failure, the PowerRouter will switch selected loads over to AC LOCAL OUT via an
external 230V relay*, providing them with power.
* Recommended external relay UK: chint – NCI – 9508 – 230 VAC or an equivalent type
Recommended external relay rest of Europe: PRA1RLY available from your local PowerRouter distributor
The mains power supplied to the PowerRouter is connected to the AC GRID terminal (see fi gure 4) and must be
between 180 and 264 VAC at a frequency of 45 to 55 Hz. Backup power is provided from the AC LOCAL OUT
connection, and the attached electrical load must be one or more 1-phase devices.
