Part #3005012

Notes:

1. The trip current for NAC1 and NAC2 is three (3) Amps, and one (1) Amp for I/O1 and I/O2.

2. The maximum voltage rating is 24 VDC.

3. The panel has ground fault detection on municipal box connection circuits. The impedance to ground for ground fault

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.
