Safety and Installation

Installation must be performed by authorized personnel in accordance with current standards. Always disconnect the power supply before performing any work inside the panel. Ensure the panel is installed in a clean area without obstacles. The panel must be kept closed during operation. Earthing must be carried out outside the panel. Use only copper conductors for external connections.

Start-up and Maintenance

Before starting, verify that there are no loose parts, dust, or dampness inside the unit. Ensure all power connections are tightened and motor guards are correctly set. During start-up, monitor for electric arcs, overheating, or unusual noises from contactors. After the first 24 hours, re-tighten all power connections. Preventive maintenance includes annual inspection of switchgear wear and re-tightening of connections. Clean the exterior with a soft cloth and mild detergent; avoid abrasive chemicals or solvents.

Troubleshooting and Wiring

If issues arise, verify the power supply and check for overheating components. The system supports various pressure switch configurations, including combined high-low pressure controllers and separate low-pressure controllers per AC input. Refer to the provided wiring diagrams for specific controller compatibility, including Danfoss, Alco, Ranco, and Penn models.
