1 Safety Instructions and Storage / Battery Care
1.1 Safety Instructions
SAVE THESE INSTRUCTIONS.
This manual contains important instructions that should be followed during installation and
maintenance of the UPS and batteries.
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. Because of small leakage currents generated by the EMI filter in
the UPS it is necessary to double check that the ground wire of the UPS is properly grounded before
connecting the UPS to the AC mains
6. This UPS is designed to be installed and commissioned in a sheltered, controlled environment as
follows:
- Ensure that the UPS is installed within the proper environmental range. (0-40°C and 0-90% non-
condensing humidity). High ambient temperature reduces battery life.
- Do not install the UPS in direct sunlight. Your warranty may be void if the batteries fail
- Do 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 m3 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.
14. To ensure safety in all applications where a UPS is hard wired to the electrical supply, ensure that the
system is installed by a qualified electrical contractor.
15. The UPS has its own internal energy source (battery). Should the battery be switched on when no AC
power is available there could be voltage at the output terminals.

aberrations experienced on utility power lines today. It is your insurance for a reliable, clean and stable
voltage supply. It is worth taking care to install the system correctly and to have it maintained correctly
by your local dealer.
22. Do not try to replacement of the battery yourself. Doing so will void your warranty. Contact your local
supplier for repairs.
23. The UPS is intended for installation in a controlled environment.
24. Install the UPS so that it is not likely to be contacted by people.
25. The maximum ambient operating temperature is 40°C or equivalent.
26. Units are considered acceptable for use in a maximum ambient 40°C
27. CAUTION - RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE
OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
28. CAUTION - Do not dispose of batteries in a fire. The batteries may explode.
29. CAUTION –Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It
may be toxic.
30. CAUTION–A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed when working on batteries:
1) Remove watches, rings, or other metal objects.
2) Use tools with insulated handles.
3) Wear rubber gloves and boots.
4) Do not lay tools or metal parts on top of batteries.
5) Disconnect charging source prior to connecting or disconnecting battery terminals.
6) Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock
can be reduced if such grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
31. External battery cabinet installation instructions, please refer to " Battery Bank Installation User's
MANUAL"

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 after-sales 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.
