APC LE1200 Line-R 1200VA Automatic Voltage Regulator User Manual

1. Introduction

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 (high voltage) 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. Safety Information

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.

• Indoor Use Only: This device is intended for indoor use in a controlled environment.
• Proper Grounding: Ensure the wall outlet used is properly grounded. Do not remove the grounding prong from the power cord.
• Avoid Overloading: 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.
• Liquid Exposure: Do not expose the unit to rain, liquids, or excessive humidity.
• Ventilation: Ensure adequate ventilation around the unit. Do not block ventilation openings.
• Servicing: Refer all servicing to qualified service personnel. There are no user-serviceable parts inside.
• Placement: Place the unit on a stable, flat surface away from direct sunlight, heat sources, and flammable materials.

3. Setup Instructions

Follow these steps to set up your APC LE1200 Automatic Voltage Regulator:

1. Select Input Voltage: Locate the input voltage 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).
2. 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.
3. Connect Your Equipment: 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.
4. 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. Operating Instructions

The APC LE1200 operates automatically to protect your connected equipment. Once powered on, it continuously monitors the incoming utility power and adjusts the voltage as needed.

Automatic Voltage Correction (AVR)

The Line-R automatically corrects voltage fluctuations by boosting low voltage (brownouts) and stepping down high voltage (overvoltages) to levels safe for your electronics. This process is typically seamless and does not interrupt power to your devices.

ON/OFF Power Switch/Circuit Breaker

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. Maintenance

The APC LE1200 Automatic Voltage Regulator requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:

• Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Ventilation: Ensure that the ventilation openings on the unit are free from dust and obstructions to prevent overheating.
• Cable Management: Keep power cords and cables neatly organized to prevent strain or damage.
• Inspection: Regularly inspect the power cord and plugs for any signs of damage. If damage is found, discontinue use and contact APC support.
