Municipal Box Connection
When programmed as a municipal box connection, the circuit power is limited, supervised for open and short circuit conditions,
and provides a local energy connection.
Municipal Box Wiring Example Figure 27.
Notes:
I/O circuits and/or NAC Circuits can be used as Municipal

Part #3005012
Notes:
The trip current for NAC1 and NAC2 is three (3) Amps, and one (1) Amp for I/O1 and I/O2. 1.
The maximum voltage rating is 24 vDC. 2.
The panel has ground fault detection on municipal box connection circuits. The impedance to ground for ground fault 3.
detection is 0 ohms.
Relay Output Wiring
The panel has three (3) dedicated common relays. The dedicated trouble relay is a fail safe trouble relay that changes position
anytime a trouble condition occurs.
Relays have a contact rating of 24vDC / 3.0A, 125vAC / 3A, and Power Factor of 1.0. These outputs are non-power limited and
not supervised.
Note: If the power supply connected to the devices is power-limited, then the outputs are power limited.
