Group B DIP Switches

B2 B1 Select AC Sharing—OPTIONAL

Your Inverter/Charger features a high-output battery charger that can draw a significant amount of AC power from your utility source or generator when charging at its maximum rate. If your unit is supplying its full AC power rating to its connected heavy electrical loads at the same time as this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-through utility power.

To reduce the chance of tripping this breaker, all APS Inverter/Chargers may be set to automatically limit the charger output. This keeps the sum of the unit’s AC load and charge power within the circuit breaker rating. This charger-limiting function has two settings, allowing you to reduce the charger’s draw lower and lower, as needed, if the AC input circuit breaker keeps tripping under the normal AC loads of devices you have connected downline from the unit. The figures show how to set your DIP Switches for charger-limiting.

Select Battery Charger-Limiting Points—OPTIONAL

(factory setting)

“Most Limiting” (#B2 & #B1 Up): B4 B3 B2 B1 Charger-limiting takes effect the moment any 120V AC load is applied; charger

output falls gradually from full output at no 120V load passing through to no output at full load.

“Less Limiting” (#B2 Up & #B1 Down):

B4 B3 B2 B1

Charger-limiting begins when the Inverter/Charger’s load reaches 33% of the Inverter/Charger’s load rating. Charger output falls gradually from full output at

33% of the Inverter/Charger’s load rating to about 40% of full output at full load.
