Municipal Box Connection
When the PSN-1000/PSN-1000(e) is programmed as a municipal box connection, the circuit is power limited and supervised for
open and short circuit conditions. It also provides a local energy connection. Please refer to the figure shown below for a wiring
example.

Relay Outputs
The board has two (2) relay outputs: a dedicated Trouble relay and a Low AC relay. The dedicated Trouble relay is a failsafe
trouble relay that changes position anytime a trouble condition occurs.
The relays have a contact rating is 24vDC / 3.0A, 125vAC / 3A, and a Power Factor of 1.0. These outputs are non-power limited
and are not supervised.
Note: If the power supply is power-limited, then the outputs are power limited.
