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.

5.1k ohm 1/2W
Part #3005012
Notes:
The trip current for NAC1–NAC6 is three (3) Amps, and one (1) Amp for I/O1–I/O4.
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 failsafe 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.
