Important Safety Instructions
SAVE THESE INSTRUCTIONS!
This manual contains important instructions and warnings that should be followed during the installation, operation and storage of all Tripp Lite
UPS Systems.
Location Warnings
• Install your UPS System (whether for a mobile or stationary application) in a location or compartment that minimizes exposure to
heat, dust, direct sunlight and moisture.
• Although your UPS System is moisture resistant, it is NOT waterproof. Flooding the unit with water will cause it to short circuit
and could cause personal injury due to electric shock. Never immerse the unit, and avoid any area where standing water might
accumulate. Mounting should be in the driest location available.
• Leave a minimum of 2" clearance at front and back of the UPS System for proper ventilation. To avoid automatic UPS System
shutdown due to overtemperature, any compartment that contains the UPS System must be properly ventilated with adequate
outside air flow. The heavier the load of connected equipment, the more heat will be generated by the unit.
• Do not install near flammable materials, fuel or chemicals.
Battery Connection Warnings
• The UPS System will not operate (with or without utility power) until batteries are connected.
• Multiple battery systems must be comprised of batteries of identical voltage, age, amp-hour capacity and type.
• Because explosive hydrogen gas can accumulate near batteries if they are not kept well ventilated, your batteries should not be
installed (whether for a mobile or stationary application) in a “dead air” compartment. Ideally, any compartment would have some
ventilation to outside air.
• Sparks may result during final battery connection. Always observe proper polarity as batteries are connected.
• Do not allow objects to contact the two DC input terminals. Do not short or bridge these terminals together. Serious personal injury
or property damage could result.
Equipment Connection Warnings
Do not use a Tripp Lite UPS System in life support or healthcare applications where a malfunction or failure of a Tripp Lite
UPS System could cause failure of, or significantly alter the performance of, a life support device or medical equipment.
• Corded models: Do not modify the UPS System’s plug or receptacle in a way that eliminates its ground connection. Do not use
power adapters that will eliminate the plug’s ground connection.
• Connect your UPS System only to a properly grounded AC power outlet or hardwired source. Do not plug the unit into itself; this
will damage the device and void your warranty.
• You may experience uneven performance results if you connect a surge suppressor, line conditioner or UPS system to the output of
the UPS System.
Operation Warnings
• Your UPS System does not require routine maintenance. Do not open the device for any reason. There are no user serviceable parts inside.
• Potentially lethal voltages exist within the UPS System as long as the battery supply and/or AC input are connected. During any
service work, the battery supply and AC input connection (if any) should therefore be disconnected.
• Do not connect or disconnect batteries while the UPS System is operating in either inverting or charging mode. Dangerous arcing may
result. Operating Mode Switch should be in the OFF position.
