1. Safety and Storage Instructions

1.1. Safety

1. Do not open the case as there are no serviceable parts inside. Opening the case will void your warranty and introduces the risk of electric shock.

2. Do not try to repair the unit yourself. Doing so will void your warranty. Contact your local supplier for repairs.

3. If liquids are spilt onto the UPS or foreign objects dropped into the unit the UPS could be damaged, users could be subject to electric stock, and the warranty will become null and void.

4. Do not install the UPS in an environment with sparks, smoke, or hazardous gas.

5. This UPS is equipped with an EMI filter. To prevent potential leakage current hazards ensure that the AC mains supply is securely grounded.

6. This UPS is designed to be installed and commissioned in a sheltered, controlled environment as follows:

- Operating temperature 0-40°C and 0-90% relative humidity. High ambient temperature reduces battery life.

- Avoid direct sunlight.

- Don not install the UPS in an inflammable or otherwise hazardous environment.

Avoid vibration and areas subject to physical impact.

- Avoid any area with sparks.

- Dusty, corrosive, and salty environments can damage any UPS.

- Install the UPS indoors as it is not designed for installation outdoors.

7. To prevent overheating of the UPS keep all ventilation openings free from obstruction, and do not place anything on top of the UPS. Keep the UPS rear panel 20 cm away from the wall or other obstructions.

8. Install the UPS in a ventilated area, ideally exchanging 5 m

of air per hour, because the chemical reaction during battery charging causes trace gas production. If the batteries suffer breakage electrical arcing could occur in the UPS interior.

9. If the product emits a strange noise or smell please immediately stop using the product and contact your dealer for maintenance.

10. Always switch off the UPS and disconnect the batteries when relocating the UPS. Be aware that, even when disconnected, charged batteries present a possible electric shock hazard.

11. The UPS should be recharged every 2-3 months if unused. If this is not done then the warranty will be null and void. When installed and being used the batteries will be automatically recharged and kept in top condition.

12 Make sure that the AC utility outlet is correctly grounded.

13. Ensure that the input voltage of the UPS matches the utility supply voltage. Use a certified input power cable with the correct plugs and sockets for the system voltage.

1.2. Storage

If the UPS is unused for an extended period of time it must be stored in a moderate climate. The batteries should be charged for 12 hours every three months by connecting the UPS to the utility supply and switching on the input breaker located on the UPS rear panel. Repeat this procedure every two months if the storage ambient temperature is above 25°C.

2. Product Introduction

2.1. General Characteristics

1. True on-line technology continuously supplies your critical device with

stable, regulated, transient-free, pure-sine-wave AC power.

2. High-efficiency PWM sine-wave topology yields excellent overall performance.

3. The high crest factor of the inverter handles all high in-rush current loads without the need to upgrade the power rating.

4. User-friendly plug-and-play design allows hassle-free installation.

5. Built-in maintenance-free, sealed batteries minimize the need for aftersales service.

6. To protect the unit from overloading, the UPS will automatically switch to bypass mode in 30 seconds if loading is at 105% of rated capacity. It will automatically switch back to inverter mode once the overload condition ceases.

7. Should the output become short-circuited the UPS puts the system in stand-by mode, provides visible and audible alarms, and cuts the output supply automatically until the short circuit situation is resolved manually.

2.2. Special Features

1. Our High Frequency Transformer-less technology and tower-convertible enclosure enables the UPS to be integrated into even the most difficult environments with space constraints.

2. This UPS is equipped with fully digital control logic for greater functionality and enhanced power protection. Digital signal processing (DSP) also provides the UPS with powerful communication capability, which simplifies remote control and monitoring.
