2. Important Safety Instructions
• Use of this equipment in life support applications where failure of this equipment can
reasonably be expected to cause the failure of the life support equipment or to significantly
affect its safety or effectiveness is not recommended.
• De-energize all input and output power sources before installing cables or making electrical
connections.
• Use flexible cable of sufficient length to permit battery cabinet servicing.
• Use ferrule caps to cover termination cables and prevent frayed ends from shorting on
terminal blocks. Use cabling rated VW-1, FT-1 or better. Use cable sleeves and connector
clamps.
• Confirm all cables are marked correctly according to their purpose, polarity and diameter.
• Observe proper polarity by following the positive and negative markings on the unit. Failure
to observe proper polarity may damage the batteries and create a serious risk of personal
injury and property damage.
• Wiring and assembly should be performed by trained, qualified electricians only. Refer to the
UPS unit's Owner's Manual for wire sizing.
Battery Warnings
• The battery cabinet does not require routine maintenance by the user. There are no user-
serviceable parts inside. Only qualified, knowledgeable service personnel familiar with all
required precautions should open the access panels for any reason. Keep unauthorized
personnel away from batteries.
• The battery cabinet contains valve-regulated recombinant lead-acid (VRLA) batteries. Do not
attempt to add water to these batteries or sample the electrolyte specific gravity.
• VRLA batteries can contain an explosive mixture of hydrogen gas. DO NOT SMOKE when
near batteries. DO NOT cause flames or sparks near batteries. Discharge static electricity
from body before touching batteries. DO NOT open or mutilate batteries—released
electrolyte is harmful to the skin and eyes and may be toxic. DO NOT dispose of batteries in
a fire—they may explode.
• Batteries present a risk of electrical shock and burns from high short-circuit current.
Battery connection or replacement should be performed only by qualified service personnel
observing proper precautions. Use tools with insulated handles. Remove watches, rings
or other metal objects. Wear rubber gloves and boots. Do not short or bridge the battery
terminals with any object. Do not lay tools or metal parts on top of batteries.
• Replace batteries with equivalent batteries (same number and type) available from
Tripp Lite.
• The batteries are recyclable. Refer to local codes for disposal requirements. Do not dispose
of batteries except through approved channels in accordance with all applicable local, state
and national regulations.
• Do not connect or disconnect batteries when the UPS system is operating from the battery
supply or when the unit is not in bypass mode. Disconnect the charging source prior to
connection or disconnecting battery terminals.
• If the charging source remains off for an extended period of time, it should be turned on
periodically to allow the batteries to recharge. The charging source should be turned on
and the batteries should be recharged at least one uninterrupted 24-hour period every
3 months. Failure to recharge the batteries periodically may cause permanent battery
damage.
