4.10 Construction

1. The enclosure shall be Polycarbonate NEMA 4X rated with lockable latches approved for indoor and outdoor environments.
2. The enclosure shall have a clear front door so control panel indicators are visible. The front panel indicators shall include green power on light, green pump run lights, and red pump fault lights. A high liquid level condition shall activate the red beacon light and 85 decibel alarm. The front panel shall include pump hand-off-auto (H.O.A.) switches, pump reset, alarm test, and silence buttons.
3. The panel shall be equipped with remote monitoring dry contacts for high liquid, pump #1 run, pump #2 run, pump #1 fault, and pump #2 fault.
