Accessory Slot: Remove the small cover panel from this slot to install optional accessories to remotely monitor and control your UPS. Refer to your accessory’s manual for installation instructions. Contact Tripp Lite Customer Support at

(773)869-1234 for more information, including a list of available SNMP, network management and connectivity products.

PowerSensitivityAdjustment: This dial is normally set fully counter-clockwise, which enables the UPS to provide maximum protection against waveform distortions in its AC input. When such distortion occurs, the UPS will normally switch to providing sine wave power from its battery reserves for as long as the distortion is present. In areas with poor utility power or where the UPS’s input power comes from a backup generator, chronic waveform distortion could cause the UPS to switch to battery too frequently, draining its battery reserves. You may be able to reduce how often your UPS switches to battery due to moderate waveform distortion by experimenting with different settings for this dial. As the dial is turned clockwise, the UPS becomes more tolerant of variations in its input power’s AC waveform. NOTE: The further the dial is adjusted clockwise, the greater the degree of waveform distortion the UPS will allow to pass to connected equip- ment. When experimenting with different settings for this dial, operate connect- ed equipment in a safe test mode so that the effect on the equipment of any wave- form distortions in the UPS’s output can be evaluated without disrupting criti- cal operations.

External Battery Connector: Use to connect Tripp Lite external battery packs for additional runtime. Refer to instructions available with the battery pack for complete connection information and safety warnings.

Output Breaker(s): Protect your UPS from output overload. If one or more breakers trip, remove some of the load on the circuit(s), then reset them by pressing the breaker switch(es) in.

Ground Screw: Use this to connect any equipment that requires a chassis ground.

Storage and Service

Storage

Before storing your UPS, turn it completely OFF. If you store your UPS for an extended period of time, recharge the UPS batteries for 4 to 6 hours once every three months. Note: after you connect the UPS to utility power, it will automatically begin charging its batteries. If you leave your UPS batteries dis- charged for an extended period of time, they will suffer a permanent loss of capacity.

Service

Before returning your UPS for service, follow these steps:

1.Review the installation and operation instructions in this manual to ensure that the service problem does not originate from a misreading of the instructions. Also, check that the UPS System’s circuit breaker(s) are not tripped. This is the most common cause of service inquiries which can be easily remedied by following the resetting instructions in this manual.

2.If the problem continues, do not contact or return the UPS to the dealer. Instead, call Tripp Lite at (773) 869-1233. A service technician will ask for the UPS's model number, serial number and purchase date and will attempt to correct the problem over the phone.

3.If the problem requires service, the technician will issue you a Returned Material Authorization (RMA) number, which is required for service. If you require packaging, the technician can arrange to send you proper packaging. Securely pack the UPS to avoid damage during shipping. Do not use Styrofoam beads for packaging. Any damages (direct, indirect, special, incidental or consequential) to the UPS incurred during shipment to Tripp Lite or an authorized Tripp Lite service center is not covered under warranty. UPS Systems shipped to Tripp Lite or an authorized Tripp Lite service center must have transportation charges prepaid. Mark the RMA number on the outside of the package. If the UPS System is within the 2-year warranty period, enclose a copy of your sales receipt. Return the UPS for service using an insured carrier to the address given to you by the Tripp Lite service technician.
