Battery Warnings
The UPS system does not require routine maintenance. There are no user-serviceable parts inside. Only qualified service personnel should open •
the access panels for any reason.
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. Turn off the UPS system before connecting or disconnecting internal
batteries. Use tools with insulated handles. Do not open the batteries. Do not short or bridge the battery terminals with any object.
Replace batteries with equivalent batteries available from Tripp Lite. Do not operate the UPS system without batteries.•
The batteries are recyclable. Refer to local codes for disposal requirements.•
Do not dispose of the batteries in a fire, mutilate the batteries or open the battery coverings.•
Battery fuses should be replaced by qualified service personnel only. Blown fuses must be replaced with the same number and type of fuses. •
Potentially lethal voltages exist within the UPS system as long as the battery supply is connected. Service and repair should be performed •
by trained personnel only, while the UPS system is turned off or placed into bypass mode. Disconnect internal batteries (if present) before
performing any service work by switching off the internal battery circuit breaker and removing the battery fuse(s). Disconnect external batteries
(if present) by switching off the external battery cabinet breaker and disconnecting the external battery cabling from the UPS system.
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.•
Do not remove the plastic sleeves covering internal batteries.•
Internal and external batteries must be replaced by equivalent batteries available from Tripp Lite.•
Before connecting an external battery cabinet to the UPS system, read the external battery cabinet’s documentation. Use only external battery •
cabinets that have been approved by Tripp Lite.
If the UPS system remains off for an extended period of time, it should be turned on periodically to allow the batteries to recharge. The UPS •
system 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 irreversible battery damage.
