Quiet Mobile Power

Congratulations! You’ve purchased the most advanced, feature-rich Inverter/Charger designed for recreational vehicle applications. Tripp Lite RV Inverter/Chargers are the quiet alternative to gas generators—with no fumes, fuel or noise to deal with! You get AC electricity anywhere and anytime you need it: rolling down the highway, dry camping in majestic back country or parked overnight at a money-saving non-electric site. RV Inverter/Chargers provide your equipment with utility- or generator-supplied AC electricity (filtered through premium ISOBAR®surge protection) whenever available. In addition, your RV Inverter/Charger automatically powers your RV’s 12V system and recharges your connected battery bank—doing what traditional RV converter/chargers do. Whenever power blackouts, brownouts or high voltages occur, your RV Inverter/Charger immediately and automatically switches over to inverting battery output to power connected AC equipment.

Important Safety Instructions

SAVE THESE INSTRUCTIONS!

This manual contains important instructions and warnings that should be followed during the installation, operation and storage of all Tripp Lite Inverter/Chargers.

Location Warnings

• Although your Inverter/Charger is moisture resistant, it is NOT waterproof. Flooding the unit with water will cause it to short circuit and could cause personal injury due to electric shock. Never immerse the unit, and avoid any area where standing water might accumulate. Mounting should be in the driest location available.

• Leave a minimum of 2" clearance at front and back of the Inverter/Charger for proper ventilation. To avoid automatic Inverter/Charger shutdown due to overtemperature, any compartment that contains the Inverter/Charger must be properly ventilated with adequate outside air flow. The heavier the load of connected equipment, the more heat will be generated by the unit.

• Do not install the Inverter/Charger directly near magnetic storage media, as this may result in data corruption.

• Do not install near flammable materials, fuel or chemicals.

• Do not mount unit with its front or rear panel facing down (at any angle). Mounting in this manner will seriously inhibit the unit's internal cooling, eventually causing product damage not covered under warranty.

Battery Connection Warnings

• Multiple battery systems must be comprised of batteries of identical voltage, age, amp-hour capacity and type.

• Because explosive hydrogen gas can accumulate near batteries if they are not kept well ventilated, your batteries should not be installed (whether for a mobile or stationary application) in a “dead air” compartment. Ideally, any compartment would have some ventilation to outside air.

• Sparks may result during final battery connection. Always observe proper polarity as batteries are connected.

• Do not allow objects to contact the two DC input terminals. Do not short or bridge these terminals together. Serious personal injury or property damage could result.

Equipment Connection Warnings

Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure of the life support equipment or to significantly affect its safety or effectiveness is not recommended. Do not use this equipment in the presence of a flammable anesthetic mixture with air, oxygen or nitrous oxide.

• You may experience uneven performance results if you connect a surge suppressor, line conditioner or UPS system to the output of the Inverter/Charger.

• Corded Models: Do not modify the Inverter/Charger’s plug or receptacle in a way that eliminates its ground connection. Do not use power adapters that will eliminate the plug’s ground connection.

• Connect your Inverter/Charger only to a properly grounded AC power outlet or hardwired source. Do not plug the unit into itself; this will damage the device and void your warranty.

• Tripp Lite recommends wiring hardwired AC output to a GFCI (ground fault circuit interrupter) protector.

• The main grounding lug should be connected to the vehicle chassis with a minimum #8 AWG wire.

Operation Warnings

• Your Inverter/Charger does not require routine maintenance. Do not open the device for any reason. There are no user serviceable parts inside.

• Potentially lethal voltages exist within the Inverter/Charger as long as the battery supply and/or AC input are connected. During any service work, the battery supply and AC input connection (if any) should therefore be disconnected.

• Do not connect or disconnect batteries while the Inverter/Charger is operating in either inverting or charging mode. Operating Mode Switch should be in the DC OFF position. Dangerous arcing may result.

Caution: These models have a failsafe AC pass-through feature where the AC output will be live (if AC input is available) even though the operating mode switch is set to DC OFF.

Configuration DIP Switches: optimize Inverter/Charger

operation depending on your application. See Configuration section for setting instructions.

Operating Mode Switch: controls Inverter/Charger operation.

The "AUTO/REMOTE" setting ensures your equipment receives constant, uninterrupted AC power. It also enables the Inverter/Charger to be remotely monitored and controlled with an optional remote module (Trip Lite model APSRM4, sold separately). The "CHARGE ONLY" setting allows your batteries to return to full charge faster by turning the inverter off which halts battery discharging. The "DC OFF" setting de-energizes the unit and connects AC OUT to AC IN. See Operation section for setting instructions.

"LINE", "INVERT", "LOAD" LEDs: show whether the

Inverter/Charger is operating from AC line power or DC battery power. It also warns you if the connected equipment load is too high. See Operation section for instructions on reading the indicator lights.

"BATT VOLTAGE" LEDs: these three lights will turn ON in

several sequences to show approximate battery level. See Operation section for instructions on reading the indicator lights.

DC Power Terminals: connect to your battery terminals. See

Battery Connection section for instructions.

Ground Fault Interrupter (GFI) AC Receptacles (not on hardwire models): allow you to connect equipment that would

normally be plugged into a utility outlet. They feature ground fault interrupter switches that trip if there is excessive current on the ground safety wire.

AC Input Cord (not on hardwire models): connects the

Inverter/Charger to any source of utility- or generator-supplied AC power. See AC Input/Output Connection section for instructions.

Hardwire AC Input/Output Terminals (not on corded models): securely connect the Inverter/Charger to vehicle or

facility electrical system input and recommended GFCI receptacle output. See AC Input/Output Connection section for instructions.

Resettable Circuit Breakers: protect your Inverter/Charger

against damage due to overload or charger failure. See Operation section for resetting instructions.

Remote Control Module Connector: allows remote monitoring

and control with an optional module (Tripp Lite model APSRM4, sold separately or included with select models). See remote module owner’s manual for connection instructions.

Battery Charge Conserver (Load Sense) Dial: conserves bat-

tery power by setting the low-load level at which the Inverter/Charger’s inverter automatically shuts off. See Configuration section for setting instructions.

Main Ground Lug: properly grounds the Inverter/Charger to

vehicle grounding system or to earth ground. See Configuration section for instructions.

Multi-Speed Cooling Fan: quiet, efficient fan prolongs equipment

service life.

Hardwire AC Input/Output Cover Plate

Battery Temperature Sensing Connector: prolongs battery life by

adjusting charge based on battery temperature. Use with cable (included on select models). See Configuration section for details.

Automatic Generator Start Connector: automatically cycles gen-

erator based on battery voltage (included on select models). Use with user-supplied cable. See Configuration section for details.

Ignition Interlock Control Jack (select models only): used to con-

nect the inverter/charger to the vehicle ignition switch. Disables AC power outlet when the vehicle ignition switch is placed in the “Engine Run” position. See p. 8 for connection instructions.

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 or included with select models) 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 prevent the inverter from drawing power from the batteries. 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 retry. Use an optional remote control module (Tripp Lite model APSRM4, sold separately) to reset unit due to overload and overtemperature.

CAUTION: The unit will always pass AC power through to connected equipment if plugged into a live AC outlet, regardless of the position of the Operating Mode Switch.

Indicator Lights

Your Inverter/Charger (as well as an optional Tripp Lite Remote Control Module, sold separately or included with select models) 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.
