Operation

Switch Modes

After configuring, mounting and connecting your Inverter/Charger, you are able to operate it by switching between the following oper- ating modes as appropriate to your situation:

AUTO/REMOTE: Switch to this mode when you

need constant, uninterrupted AC power for connected equipment. The Inverter/Charger will continue to supply

AC power to connected equipment and to charge your connected batteries while utility- or generator-sup- plied 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 situa- tions. “AUTO/REMOTE” also enables an optional remote control module (Tripp Lite model APSRM4, included) to function when con- nected to the unit.

CHARGE ONLY: Switch to this mode when you are not using connected 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-suppliedAC power is present.

However, since the inverter is OFF in this mode, it WILL NOT sup- ply AC power to connected equipment in the absence of a utility/gen- erator source or in over/under voltage situations.

OFF: Switch to this mode to shut down the Inverter/Charger completely, preventing the inverter

from drawing power from the batteries, and preventing

utility AC from passing through to connected equip- ment or charging 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 “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 the remote control module (Tripp Lite model APSRM4, included) to reset unit due to overload only.

Indicator Lights

Your Inverter/Charger (as well as the Tripp Lite Remote Control Module, included) 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 the charge condition of your batteries, as well as ascertain operating details and fault conditions.

LINE Green Indicator: If the operating mode switch is set to “AUTO/REMOTE”, this light will ILLUMI- NATE CONTINUOUSLY when your connected equipment is receiving continuous AC power sup- plied from a utility/generator source.

If the operating mode switch is set to “CHARGE ONLY”, this light will FLASH 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 Indicator: This light will ILLUMINATE CONTINUOUSLYwhenever 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 FLASH to alert you if the load is less than the Battery Charge Conserver (Load Sense) setting.

LOAD Red Indicator: This red light will ILLUMI- NATE CONTINUOUSLY whenever the inverter is functioning and the power demanded by connected appliances and equipment exceeds 100% of load capacity. The light will FLASH to alert you when the inverter shuts down due to a severe overload or overheating. If this hap- pens, 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.

BATTERY Indicator Lights: These three lights will illuminate in several sequences to show the approximate charge level of your con- nected battery bank and alert you to two fault conditions:

Approximate Battery Charge Level*
	Indicator Illuminated	Battery Capacity
		(Charging/Discharging)
1	Green	91%–Full
2	Green & Yellow	81%–90%	1	2	3
3	Yellow	61%–80%
4	Yellow & Red	41%–60%
5	Red	21%–40%	4	5	6
6	All three lights off	1%–20%

7	Flashing red	0% (Inverter
		shutdown)

*Charge levels listed are approximate. Actual conditions vary depending on battery condition and load.

Fault Condition

		Indicator Illuminated	Fault Condition
1		All three lights	Excessive discharge
		flash slowly*	(Inverter shutdown)
	2	All three lights	Overcharge (Charger
		flash quickly**	shutdown)	1	2

*Approximately ½ second on, ½ second off. See Troubleshooting section. ** Approximately ¼ second on, ¼ second off. May also indicate a battery charger fault exists. See Troubleshooting section.

Resetting Your Inverter/Charger to Restore AC Power

Your Inverter/Charger may cease supplying AC power or DC charging power in order to protect itself from overload or to protect your elec- trical system. To restore normal functioning:

Overload Reset: Switch operating mode switch to “OFF” and

remove some of the connected electrical load (ie: turn off some of the AC devices drawing power which may have caused the overload of the unit). Wait one minute, then switch operating mode switch back to either “AUTO/REMOTE” or “CHARGE ONLY.”

Output Circuit Breaker Reset: Alternatively, check output circuit breaker(s) on the unit's front panel. If tripped, remove some of the elec- trical load, then wait one minute to allow components to cool before resetting the circuit breaker. See Troubleshooting for other possible

reasons AC output may be absent.
