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 mod- erate 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 con- nected equipment. When experimenting with different settings for this dial, operate connected equipment in a safe test mode so that the effect on the equip- ment of any waveform distortions in the UPS’s output can be evaluated without disrupting critical operations.

External Battery Connector (Select Models Only): Use to connect Tripp Lite external battery packs for additional runtime. The specifications section of this manual lists the Tripp Lite external battery packs that are compatible with your model. Refer to instructions available with the battery pack for complete con- nection information and safety warnings.

Input Breaker(s) (all models): Protect your electrical circuit from overcurrent draw from the UPS load. If these breakers trip, remove some of the load, then reset them by pressing the breaker(s) in.

Output Breaker (select models): Your UPS features one or more breakers that 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.
