DIP SWITCH GROUP B (Available on Select Models)

LOAD SHARING/EQUALIZE BATTERY CHARGE

The “Load Sharing” Configuration DIP Switches, #1 and #2 of Group B (located on the front panel of your APS; see Diagram 1, p. 36), should be set with a small tool according to the guide- lines below. DIP Switch #3, Group B should be kept in the “UP” position when you are not equal- izing your batteries' charges. DIP Switch #4, Group B has different functions, or no function, depending on your APS model.

•Load Sharing (DIP Switches #1, Group B & #2, Group B)

Your APS features a high-output battery charger that can draw a significant amount of power from your line power source when charging at its maximum rate. If an APS is supplying its full AC power rating to its connected load at the same time as it is charging, it could trip its line source circuit breaker. Tripping this breaker will cut off AC power to your load and stop battery charging.

To reduce the chance of tripping this breaker, select APS models may be set to automatically limit their charger output to keep the sum of their AC load and charger power within their circuit breakers’ rating.

This charger limiting function has four settings, allowing you to choose less charger limiting for APS configurations with higher rated breakers. The figures below show how to set your DIP Switches to select how heavy a load can be placed on your APS before charger limiting begins.

Battery Charger Limiting Points

Most Limiting (#1 & #2 Up*): Charger limiting takes effect the moment any load is applied; charger output falls gradually from full output at no load to no output at full load.

Less Limiting (#1 Down & #2 Up): Charger limiting begins when the APS's load reaches 33% of the APS’s load rating. Charger output falls gradually from full output at 33% of the APS's load rating to about 40% of full output at full load.

Least Limiting (#1 Up & #2 Down): Charger limiting begins at when the APS’s load reaches 66% of the APS’s load rating. Charger output falls gradually from full output at 66% of the APS's load rating to about 40% of full output at full load.

No Limiting (#1 & #2 Down): No charger limiting occurs at any load size.
