This UPS has been designed and constructed to protect your assets from the wide 

range of power aberrations experienced on Utility power lines today.    It is your 
insurance for reliable, clean and stable voltage supply.    It is important to install the 
system correctly and to have it maintained correctly by your local distributor.   

Chapter 1.  IMPORTANT SAFETY 

INSTRUCTIONS 

 WARNING: 

This is a Class A-UPS Product and may cause radio interference to other home 
appliances. User are advised to take additional measures and check with their local

SAVE THESE INSTRUCTIONS

 

 

 

 

This manual contains important instructions that should be followed during 
installation and maintenance of the UPS and batteries. 

 

Servicing of Batteries Should be Performed or Supervised by Trained Personnel with 

Knowledge of Batteries and the Required Precautions   

 

 

When Replacing Batteries, Replace With the Same Quantity, Type & Capacity. 

An Important Notice 

 

CAUTION – Do Not Dispose of Battery or Batteries in an open fire. The Battery May 

Explode. 

 

 

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.   

 

CAUTION – Do not open or mutilate the batteries. The electrolyte from the batteries is 

toxic and harmful to the skin and eyes.   

 

The UPS systems which are supplied with a factory input plug can be safely connected 
to the wall receptacle by the user.   

 

CAUTION – Risk of Electric Shock – Battery Circuit is not isolated from AC, hazardous 

Voltage may exist between battery terminals and ground. Test before touching with 
bare hands. 

 

This UPS is connected to an internal/external battery bank. There will be voltage at the 

output terminals if the UPS is turned on even if the input AC Mains is not available.   

 

CAUTION – A Battery can present a Risk of Electrical Shock and High Short Circuit 

Current.    The Following Precaution Should be Observed When Working on Batteries: 

 

Make sure that the AC Utility outlet is correctly grounded.   

 

Do not try to repair the unit yourself, contact your local supplier or your warranty will be 

void.  

A.  Remove watches, rings, or other metal objects. 
B.  Use tools with insulated handles. 

 

Please make sure that the input voltage of the UPS matches the supply voltage.   

C.  Wear rubber gloves and boots. 
D.  Do not lay tools or metal parts on top of batteries. 

 

Use a certified input power cable with the correct plugs and sockets for the appropriate 

voltage system.   

E.  Disconnect charging source prior to connecting or disconnecting battery terminals. 

 

CAUTION – To reduce the risk of fire, connect only to a circuit provided with 50 

amperes maximum branch circuit over-current protection in accordance with 
the National Electric Code, ANSI/NFPA 70.( 3KRT) 

 

To eliminate any overheating of the UPS, keep all ventilation openings free from 

obstruction and do not place any foreign objects on top of the UPS. Keep the UPS   

20 cm away from the wall.   

 

Make sure the UPS is installed within the proper environment as specified. (0-40

°

C and 

30-90% non-condensing humidity) 

 

Do not install the UPS under direct sunlight.    Your warranty will be void if the batteries 

fail due to overheating. 

 

This UPS system is designed for indoor use only. 

 

This UPS system is not design for use in dusty, corrosive and salty environments .   

 

The warranty for this UPS will be void if water or other liquid is spilt or poured directly 

onto the UPS. Similarly we do not warrant any damage to the UPS if foreign objects are 
deliberately or accidentally inserted into the UPS enclosure.   

 

The battery will discharge naturally if the system is unused for a period of time. 

 

It should be recharged every 2-3 months if unused. If this is not done, then the 

  warranty will be null and void.    During normal operation, the batteries will be   

automatically remained in charged condition.   

 

This UPS supports electronic equipment in offices, telecommunication, process control, 

medical and security applications.
