8. DC Power Terminals: These terminals should be wired to your battery terminals. See
“Battery Connection”, p. 9 for instructions.
9. AC Receptacles: NEMA 5-15R (Corded models only): These receptacles 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. If
the switches trip, press them to reset them when the short circuit situation is remedied.
10. AC Input Line Cord: NEMA 5-15P fixed (Corded models only): This cord should be
plugged into a 120V, 60 Hz, dedicated 15 Amp AC utility outlet. DO NOT plug the cord into
the APS’s AC receptacles.
11. 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 p. 10 &
35 for wiring instructions.
12. Resettable Circuit Breakers: 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 pre-
vent overload, then wait 1 minute to allow components to cool before resetting the circuit
breaker.
13. Remote Module Connector: The front panel has an RJ45 receptacle for use with the option-
al remote module. See the installation instructions packed with the remote module.
14. Load Sense Potentiometer: 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 clockwiseto lower the min-
imum 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 detect-
ed, causing the inverter to stay off until the new minimum load is reached. The factory set-
ting 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 opera-
tion when the APS’s load is in use.
15. Ground Bond Connector (Hardwired models only): This connector is used to ensure that
both conduits have a permanent connection to ground.
16. Ground Connector Block: Use this block to connect the grounding cables of supported
equipment.
