Load Sharing

(DIP Switches #1, Group B & #2, Group B)

Your APS features a high-outputbattery charger that can draw a significantamount of power from your line power source when charging at its maximum rate. If an APS is supplying its full AC powerratingto itsconnectedloadatthe sametime as itischarging, itcouldtrip itslinesource circuit breaker.Trippingthis breaker will cutoff AC powerto your loadandstopbatterycharging.

--- To reduce thechanceof tripping this breaker, select APS models may be set to automatically limit their charger output to keep the sum of their AC loadand charger powerwithintheir circuit breakers' rating.

This charger limiting function has four settings, allowing you to choose less charger limiting for APS configurationswith 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.

Select a battery or system of batteries that will provide your APS with proper DC voltage and an adequate amp hour capacity: Select 'Deep-Cycle' batteries to enjoy optimum performancefrom your APS. Batteriesof either Wet-Cell (vented) or Gel-CelVAbsorbedGlass Mat (sealed)construction are ideal. 6 Volt "golf-cart," Marine Deep-Cycle or 8D Deep-Cycle batteries are also acceptable."

Compensate for inefficiency by multipling your Battery Amp-Hour Required Rough Estimate (from Step 3) by 1.2 to determine how many amp-hours of batterybackup (fromone or severalbatteries) you should connect to your APS." Note that the Amp-Hour ratings of batteries are usually given

Equalize Battery Charge

(DIP Switch #3, Group B)

This DIP Switch allows you to equalize the internal resistance of your battery'scells. The

.process is automatic and once started can only be stopped by removing the input power.

SElTiNG PROCEDURE:

1)Move to 'Equalize' (DOWN)position for three seconds.

2)Move to 'Reset' (UP)position and leave it there.

CAUTION:Battery charge equalizationshould only beperformed in strict accordance with the battery manufacturer's instructions and speciflations.
