SAVE THESE INSTRUCTIONS 

 

 This manual contains important instructions for the GES-801L, GES-102L, GES-152L, GES-202L, 

GES-302L and should be followed during installation and maintenance of the UPS and batteries. 

 The UPS contains voltages that are potentially hazardous.  Please contact our dealers or qualified 

personnel for service. 

 Servicing of the batteries should be performed or supervised by personnel knowledgeable with batteries 

and the required precautions. Keep unauthorized personnel away from batteries. 

 When replacing batteries, replace with the same model number, type and rating. 
 CAUTION: Do not dispose of the batteries in a fire. The batteries may explode. 
 CAUTION: Do not open or mutilate the batteries. Released electrolyte is harmful to the skin and eyes.  

It may be toxic. 

 CAUTION: A battery can present a risk of electrical shock and high short circuit current.  The 

following precautions should be observed when working on or with the batteries. 

−  Remove watches, rings, or other metal objects. 

−  Use tools with insulated handles. 

−  Wear rubber gloves and boots. 

−  Do not lay tools or metal parts on top of batteries. 

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

−  Determine if the batteries are inadvertently grounded.  If inadvertently grounded, remove source of 

ground. Contact with any part of a grounded battery can result in electric shock. The likelihood of a 
shock will be reduced if grounds are removed during installation and maintenance (applicable to a UPS 
and a remote battery supply not having a grounded supply circuit).  

 CAUTION: To ensure the safety and performance of the UPS, never load the UPS with a hair dryer, 

heater, laser printer, Surge protector or other types of inductive loads.
