1. Introduzione
The APC LE1200 Line-R 1200VA Automatic Voltage Regulator (AVR) is designed to protect your electronic equipment from voltage fluctuations. It automatically corrects brownouts (low voltage) and overvoltages (alto volumetage) from the power utility service, ensuring a stable and safe power supply for computers and other sensitive devices. This manual provides essential information for the proper installation, operation, and maintenance of your LE1200 unit.

2. Informazioni sulla sicurezza
Please read and understand these safety instructions before installing or operating the APC LE1200. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Solo per uso interno: This device is intended for indoor use in a controlled environment.
- Messa a terra corretta: Ensure the wall outlet used is properly grounded. Do not remove the grounding prong from the power cord.
- Evitare il sovraccarico: Do not exceed the maximum output power capacity specified for this unit. Overloading can cause the circuit breaker to trip or damage the unit and connected equipment.
- Esposizione al liquido: Do not expose the unit to rain, liquids, or excessive humidity.
- Ventilazione: Assicurare un'adeguata ventilazione attorno all'unità. Non ostruire le aperture di ventilazione.
- Manutenzione: Per qualsiasi intervento di manutenzione, rivolgersi a personale qualificato. All'interno non sono presenti parti riparabili dall'utente.
- Posizionamento: Place the unit on a stable, flat surface away from direct sunlight, heat sources, and flammable materials.
3. Istruzioni per l'installazione
Follow these steps to set up your APC LE1200 Automatic Voltage Regolatore:
- Seleziona Input Voltage: Individuare il volume di inputtage selector switch on the unit (if applicable, refer to the unit's labeling for exact location). Set it to match your local utility voltage (e.g., 120V for North America).
- Plug the Line-R into a Wall Outlet: Connect the power cord of the LE1200 directly into a properly grounded wall outlet. Avoid using extension cords or power strips for the LE1200's input.
- Collega la tua attrezzatura: Plug your electronic devices (computers, monitors, audio equipment, etc.) into the output receptacles on the back of the LE1200. Ensure the total power consumption of all connected equipment does not exceed the unit's maximum output capacity.
- Switch ON the Line-R: Press the ON/OFF power switch located on the unit to turn it on. The indicator lights will illuminate, signifying that the unit is operational and providing regulated power.

4. Istruzioni per l'uso
The APC LE1200 operates automatically to protect your connected equipment. Once powered on, it continuously monitors the incoming utility power and adjusts the voltage secondo necessità.
Volume automaticotage Correction (AVR)
The Line-R automatically corrects voltage fluctuations by boosting low voltage (brownouts) and stepping down high voltage (sovravoltages) to levels safe for your electronics. This process is typically seamless and does not interrupt power to your devices.
ON/OFF interruttore di alimentazione/interruttore automatico
The unit features an integrated ON/OFF power switch that also functions as a circuit breaker. This switch controls the power supply to all connected devices. In the event of an overload condition (when the total power consumption of connected equipment exceeds the unit's capacity), the circuit breaker will trip, automatically cutting power to protect the unit and your devices. To reset, reduce the load and press the switch back to the 'ON' position.
5. Manutenzione
The APC LE1200 Automatic Voltage Regulator requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Pulizia: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Ventilazione: Ensure that the ventilation openings on the unit are free from dust and obstructions to prevent overheating.
- Gestione dei cavi: Keep power cords and cables neatly organized to prevent strain or damage.
- Ispezione: Regularly inspect the power cord and plugs for any signs of damage. If damage is found, discontinue use and contact APC support.
6. Risoluzione Dei Problemi
This section addresses common issues you might encounter with your APC LE1200.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| L'unità non si accende. | Power cord not securely plugged in; Wall outlet has no power; ON/OFF switch is off. | Ensure power cord is fully inserted. Test wall outlet with another device. Press the ON/OFF switch to the 'ON' position. |
| Circuit breaker trips (power cuts off). | Overload condition (too many devices or high-power devices connected). | Disconnect some equipment to reduce the load. Wait a few moments, then press the ON/OFF switch to reset the circuit breaker. Ensure total load does not exceed 1200VA. |
| Unit makes clicking noises. | Normal operation during voltage correzione. | This is normal. The unit's internal relays are engaging to adjust the voltage. No action required. |
| Connected equipment still experiences power issues. | Voltage fluctuations outside the unit's correction range; Faulty equipment. | Verificare il volume immessotage selector is set correctly. If issues persist, contact APC support or an electrician to check your home's wiring. Test equipment directly in a known good outlet. |
