Maintenance 113

Regularmaintenance of the battery module is an absolutenecessity. Periodic inspectionsof battery and terminal

voltages,specific gravity, and connectionresistance should be made. Strictly follow the proceduresoutlined in

the battery manufactu rer’s manual.

Valve-regulatedlead-acid (sealed-top)batteries do require periodic maintenance. Though theydo not require

maintenanceof electrolyte levels, battery voltageand connection resistance checks should be made.

Sinceindividual battery characteristicsare not identical, and may change over time, the UPS module is equipped

withcircuitry to equalize battery cell voltages. This circuitincreases charging voltage to maintain flooded type

battery cells at full capacity.

Theequalizing charge time period is adjustable from zero to 72 hours and can be initiatedautomatically or man-

ually.Refer to 3.0 - Operation.

NOTE

Donot use equalize charging with valve-regulatedlead-acid batteries.

Consultthe battery manufacturer's manual for specificinformation about equalize

charging.
