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 gure
shown below for a wiring example.
CongurationCharacteristics
y NAC1-NAC6's trip current is 3 amps.
y Maximum voltage rating is 24 VDC.
Notes:
1. e panel has ground fault detection on municipal box connection circuits.
2. e impedance to ground for ground fault detection is 0 ohms.

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