11.1 Maintenance Safety Warnings
• The UPS is designed to supply power even when disconnected from utility power. Only authorized service personnel may
access the interior of the UPS, after disconnecting the utility and DC power.
• Battery replacement should be performed only by authorized service personnel using the same number and type of batteries
(sealed lead-acid).
• Do not disconnect the batteries while the UPS is in Battery mode.
• Disconnect the charging source prior to connecting or disconnecting terminals.
• Batteries can present a risk of electrical shock or burn from high short-circuit current.
• The following PRECAUTIONS should be observed:
1. Remove watches, rings or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and rubber-soled footwear.
4. Do not lay tools or metal parts on top of batteries or battery cabinets.
5. Disconnect the charging source prior to connecting or disconnecting terminal.
6. Determine if the battery is inadvertently grounded. If it is, remove the source of the ground. Contact with any part of a
grounded battery can result in electrical shock. The likelihood of such shock is reduced if such grounds are removed
during installation and maintenance.
11.2 UPS
Cleaning
Regularly clean the UPS, especially the vents and openings, to ensure air flows freely into the UPS to avoid overheating. If
necessary, use compressed air to clean the vents and openings to prevent any object from blocking or covering these areas.
Fan
Higher temperatures shorten fan life. When the UPS is running, ensure each fan works normally and make sure air can move
freely around and through the UPS.
Note: Contact Tripp Lite Tech Support for more maintenance information. Do not perform maintenance if you are not qualified to do so.
Regular Inspection
Check the UPS every six months and inspect:
1. The UPS, LEDs and alarm function for normal operation.
2. Battery voltage; if battery voltage is too high or too low, see Troubleshooting table in Section 9.
Possible Cause
The UPS is overloaded.
Batteries are damaged or battery life
has expired.
The AC input voltage or frequency is
out of the acceptable range.

Solution
Remove some of the connected loads.
Contact Tripp Lite Tech Support.
1. Check whether the AC input voltage or
frequency is abnormal.
