Operation Switch Modes After configuring, mounting and connecting your Inverter/Charger, you are able to operate it by switching between the following operating modes as appropriate to your situation: AUTO/REMOTE: Switch to this mode when you need constant, uninterrupted AC power for connected appliances and equipment. The Inverter/Charger will continue to supply AC power to connected equipment and to charge your connected batteries while utilityor generator-supplied AC power is present. Since the inverter is ON (but in Standby) in this mode, it will automatically switch to your battery system to supply AC power to connected equipment in the absence of a utility/generator source or in over/ under voltage situations. "AUTO/REMOTE" also enables an optional remote control module (Tripp Lite model APSRM4, sold separately) to function when connected to the unit. CHARGE ONLY: Switch to this mode when you are not using connected appliances and equipment in order to conserve battery power by disabling the inverter. The Inverter/Charger will continue to supply AC power to connected equipment and charge connected batteries while utility- or generator-supplied AC power is present. However, since the inverter is OFF in this mode, it WILL NOT supply AC power to connected equipment in the absence of a utility/generator source or in over/under voltage situations. DC OFF: Switch to this mode to shut down the Inverter/Charger, preventing the inverter from drawing power from the batteries, and preventing utility AC from charging the batteries. The "DC OFF" position connects AC OUT to AC IN, providing failsafe pass-through power. Use this switch to automatically reset the unit if it shuts down due to overload or overheating. First remove the excessive load or allow the unit to sufficiently cool (applicable to your situation). Switch to "DC OFF", then back to "AUTO/ REMOTE" or "CHARGE ONLY" as desired. If unit fails to reset, remove more load or allow unit to cool further and try again. Use an optional remote control module (Tripp Lite Model APSRM4, sold separately) to reset unit after shutdown due to due to overload or overheating. Caution: Your Inverter/Charger has a failsafe AC pass-through feature. The AC output will be live (if AC input is available) even though the operating mode switch is set to DC OFF. Indicator Lights Your Inverter/Charger (as well as an optional Tripp Lite Remote Control Module, sold separately) is equipped with a simple, intuitive, user-friendly set of indicator lights. These easily-remembered "traffic light" signals will allow you, shortly after first use, to tell at a glance a wide variety of operating details. "LINE Green LED": If the operating mode switch is set to "AUTO/ REMOTE", this light will ILLUMINATE CONTINUOUSLY when your connected equipment is receiving continuous AC power supplied from a utility/generator source. If the operating mode switch is set to "CHARGE ONLY", this light will BLINK to alert you that the unit's inverter is OFF and will NOT supply AC power in the absence of a utility/generator source or in over/under voltage situations. "INV" (Inverting) Yellow LED: This light will ILLUMINATE CONTINUOUSLY whenever connected equipment is receiving battery-supplied, inverted AC power (in the absence of a utility/ generator source or in over/under voltage situations). This light will be off when AC power is supplying the load. This light will BLINK to alert you if the load is less than the Battery Charge Conserver (Load Sense) setting. "LOAD" Red LED: This red light will ILLUMINATE CONTINUOUSLY whenever the inverter is functioning and the power demanded by connected appliances and equipment exceeds 100% of load capacity. The light will BLINK to alert you when the inverter shuts down due to a severe overload or overheating. If this happens, turn the operating mode switch "OFF"; remove the overload and let the unit cool. You may then turn the operating mode switch to either "AUTO/REMOTE" or "CHARGE ONLY" after it has adequately cooled. This light will be off when AC power is supplying the load. "BATT VOLTAGE" LEDs: If the operating mode switch is in the "AUTO/REMOTE" or "Charge Only" position, the LEDs indicate the approximate charge level and voltage of your connected battery bank and alert you to several fault conditions. See Chart for charge and voltage levels. LED Function with Switch in "AUTO/REMOTE" or "Charge Only" Position Approximate Battery Charge Level* LEDs Illuminated 1 Green 2 Green & Yellow Battery Capacity (Charging/Discharging) 91%-Full 81%-90% 1 2 3 3 Yellow 61%-80% 4 Yellow & Red 41%-60% 5 Red 6 All three lights off 21%-40% 1%-20% 45 6 7 Flashing red 0% (Inverter shutdown)** 7 * Charge levels listed are approximate.

See Troubleshooting section. Inverter shutdown protects battery against damage due to excessive discharge.** Approximately ¼ second on, ¼ second off. Charger shutdown protects battery against damage due to overcharge. May also indicate a battery charger fault exists. See Troubleshooting section. 4
