8.“BATTERY HI/MED/LO” (All models)
These three lights will turn ON in several sequences to show the approximate charge level and
voltage of your connected battery bank and alert you to several fault conditions:
BATTERY CHARGE INDICATION (Approximate)
Indicator Capacity
Green 91% - Full
Green & yellow 81% - 90%
Yellow 61% - 80%
Yellow & red 41% - 60%
Red 21% - 40%
All three lights off 1% - 20%
Flashing red 0% (Inverter shutdown)
All three lights flash slowly* Excessive discharge
All three lights flash quickly** Overcharge
* Approximately 1/2 second on, 1/2 second off. See Troubleshooting section.
** Approximately 1/4 second on, 1/4 second off. May also indicate a battery charger fault exists. See Troubleshooting section.
Other Features
9. DC Input Terminals (All models)
The terminals' lug screws secure the wires leading from your external battery or battery system.
Your battery or battery system must provide your APS with proper DC voltage and your equipment
with an adequate amp hour capacity. See Battery Selection section, pg. 7 for more information.
10.
AC Receptacles: IEC 320 (Corded models only)
These IEC receptacles allow you to connect equipment that would normally be plugged into a util-
ity outlet. For other plug configurations, use an adapter that provides a connection to ground.
11.
AC Input: IEC 320 (Corded models only)
This IEC receptacle should be connected to a dedicated 15 Amp AC utility outlet via an adapter
cord that provides a connection to ground . A detachable IEC to 5-15 cord is provided for this pur-
pose. DO NOT plug the cord into the APS’s AC receptacles.
12.
Hardwire AC Input/Output Terminal Strip (Hardwire models only)
Use the lug screws on these terminals to secure hardwire connections for AC input and output.
See pages 9 & 32 for wiring instructions.
13.
Resettable Circuit Breakers (All models)
These circuit breakers protect your APS against damage due to input or output overload. If a
breaker trips, remove some of the load on the APS to prevent overload, then wait 1 minute to allow
components to cool before resetting the circuit breaker.
14.
Remote Module Connector (All models)
The front panel of all models has an RJ 45 receptacle for use with the optional remote module.
(Module is included with all VR models.) See the installation instructions packed with the remote
module.
15.
Load Sense Potentiometer (All models)
In order to save battery power, the APS’s inverter automatically shuts off when no load is
connected. When the unit detects a load, it automatically turns the inverter on. Users may choose
the minimum load the APS will detect by adjusting the Load Sense Potentiometer. Using a small
tool, turn the potentiometer clockwise to lower the minimum load that will be detected, causing the
inverter to turn on for smaller loads.When the potentiometer is turned fully clockwise, the inverter
will operate even when there is no load. Turn the potentiometer counterclockwise to increase the
minimum load that will be detected, causing the inverter to stay off until the new minimum load is
reached. The factory setting for the potentiometer is fully clockwise, but in areas with frequent
power interruptions, the potentiometer should be adjusted counterclockwise until the inverter is
only in operation when the APS’s load is in use.
